Ecological significance of soil pH. Soil pH is important to plant growth because it influences the availability of essential nutrients. It is considered as an indicator of soil health. It affects crop yields, crop suitability, plant nutrient availability, and …
A biome is a major regional or global community of organisms characterized by climate conditions nad plant communities that thrive there What are the Earth’s biomes? Tropical Rain Forest, Temperate Rain Forest, Taiga, Savanna , Grasslands , Desert, Fresh Water , Marine , Coral Reef, Tundra ( Biomes share the same , animals , plants, weather.)
An important ecological function of plants is that they produce organic compounds for herbivores in the bottom of the food web. A large number of plant traits, from thorns to chemical defenses, can be related to the intensity of herbivory. Large herbivores can also have many effects on vegetation.
The major quantitative characters include frequency, diversity, cover, biomass, leaf size, abundance, dominance, etc.
Community Ecology Examples Community ecology encompasses many types of ecological interactions that continue to change over time. A forest community includes the plant community, all trees, birds, squirrels, deer, foxes, fungi, fish in a forest stream, insects and all other species living there or migrating seasonally.Jun 4, 2019
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
They release oxygen into the atmosphere, absorb carbon dioxide, provide habitat and food for wildlife and humans, and regulate the water cycle [1]. Because of the many ways plants help the environment, their importance should not be forgotten.Nov 23, 2016
An ecological community is a group of actually or potentially interacting species living in the same location. Communities are bound together by a shared environment and a network of influence each species has on the other. Community ecology is an expanding and rich subfield of ecology.
An ecological community is defined as a group of actually or potentially interacting species living in the same place. A community is bound together by the network of influences that species have on one another.
Ecosystem ecologists look at relationships between organisms and their environment. For example, in an aquatic ecosystem, an ecosystem ecologist might examine the relationships between the aquatic environment and the plants and animals that call it home.Feb 4, 2022
Some of the major characteristics of a community ecology are as follows: (a) Species Diversity (b) Growth From and structure (c) Dominance (d) Self reliance (e) Relative abundance (f) Trophic structure. Community ecology deals with the group of various kinds of population in the areas.
No single species on Earth lives without interacting with other species. These interactions are the backbone of biodiversity and create the architectural foundation of ecosystems. Exploring and inventorying biodiversity represent a fundamental challenge for basic research in ecology and conservation biology.Sep 15, 2016
Community ecology focuses on the processes driving interactions between differing species and their overall consequences. Ecosystem ecology studies all organismal, population, and community components of an area, as well as the non-living counterparts.Aug 14, 2020
An ecosystem is all the living organisms and environmental factors that interact within a given area. A community is only the living organisms that interact within a given area.
Plants recycle matter in biogeochemical cycles. For example, through transpiration , plants move enormous amounts of water from the soil to the atmosphere. Plants such as peas host bacteria that fix nitrogen. This makes nitrogen available to all plants, which pass it on to consumers.
Members of the plant kingdom play many crucial and sometimes surprising roles in the drama of life on Earth. You are probably familiar with some reasons plants are important. Why should you understand how plants live? Because plants play many roles, including but certainly not limited to: 1 Supplying Food and Energy 2 Maintaining Earth’s Atmosphere 3 Cycling Water and Nurturing Soils 4 Contributing to Nitrogen and Other Biogeochemical Cycles 5 Interdependence with Animals 6 Interdependence with Fungi 7 Interdependence Among Plants 8 Resources for Humans 9 Aesthetics for Humans 10 Scientific Use by Humans 11 Causing Problems
Oxygen is essential for cellular respiration for all aerobic organisms. It also maintains the ozone layer that helps protect Earth’s life from damaging UV radiation. Removal of carbon dioxide from the atmosphere reduces the greenhouse effect and global warming. Plants recycle matter in biogeochemical cycles.
Plants provide many products for human use, such as firewood, timber, fibers, medicines, dyes, pesticides, oils, and rubber. Plants create habitats for many organisms.
People often introduce plants to new habitats where they lack natural predators and parasites. The introduced plants may spread rapidly and drive out native plants. Many plants produce pollen, which can cause allergies. Plants may also produce toxins that harm human health (see Figure below ).
pollen. tiny grains that bear the male gametes of seed plants and transfer sperm to female reproductive structures. photosynthesis. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar.
More than 100,000 natural compounds come from plants, and most of these have yet to be explored. Some of the most powerful and useful compounds come from plants. Who knew they could help us unlock some of the biology's mysteries - all using an approach of mapping biological pathways.
Composting is controlled decomposition that can be used in the garden as mulch or soil. It depends on microorganisms to feed on and break down plant debris. In order to do this the microorganisms also need oxygen and moisture. Microorganisms need a combination of materials rich in carbon (fallen leaves, branches, and twigs) and nitrogen (such as kitchen scraps). Reducing the particle size of the raw materials will increase the speed of the composting process. The proper mix of materials should result in a hot (135-160oF) compost pile which will destroy weeds seeds and diseases. When incorporated back into the soil, compost increases the soils ability to retain moisture, improves drainage and aeration, supplies small amounts of nutrients, and increases the biological activity of soil organisms.
Forests, lawns, streams, and marshes are all habitats that are easily recognized as unique biotic communities. A community is a naturally occurring, interactive assemblage of plants and animals living in the same environment. The interaction between plants and animals often exists out of the need for food, protection, transportation, and reproduction. The different kinds of interaction possible between organisms are extremely important in determining the abundance of species. If the interaction between species is beneficial, it is described as mutualism. Some of the most complex mutualistic relationships evolved between plants and pollinators. If the interaction proves disadvantageous, it is referred to as competition.Commensal relationships, in which one species benefits and the other is unaffected, are common between plants and animals. For example, when a bird builds a nest in a tree, the bird benefits and the tree is (usually) unharmed. Other relationships may positively affect one population and be detrimental to the other. Such relationships involve predation and parasitism. In predation, one organism directly kills and consumes its prey. Parasitism differs in that parasites live on or in the prey, but may not kill it outright. A good example of parasitism is mistletoe growing on a tree.
This equation as interpreted as six molecules of carbon dioxide and twelve molecules of water react in the presence of chlorophyll and light to form one molecule of glucose, and six molecules of oxygen.
A beautiful landscape doesn't just happen, it must be planned!! The first step in designing a landscape is to decide how the landscape is or will be used. Landscapes can screen unsightly views, increase property value, provide privacy and attract birds and other wildlife. The next step is to draw a bird's eye sketch of the area on a piece of paper. Include the location of property lines, structures, and existing plants on the sketch. Use the sketch to record characteristics about the site such as sunlight patterns, soil characteristics, water runoff and utility lines. Once you have prioritized your needs and examined your landscape site, you are ready to create the landscape plan. Draw in lines that separate the lawn from the landscape, then add trees, ground covers, and shrubs. Use colors, textures, and shapes of plants to create interest and draw attention to a particular area in a landscape. Attention must also be given to the proportion or size of a plant in relation to its surroundings .
Plants provide us with food, fiber, shelter, medicine, and fuel. The basic food for all organisms is produced by green plants. In the process of food production, oxygen is released. This oxygen, which we obtain from the air we breathe, is essential to life. The only source of food and oxygen are plants; no animal alone can supply these. Shelter, in the form of wood for houses; and clothing, in the form of cotton fibers, are obvious uses of plant materials. But we must not forget fuel, furniture, paper products, certain medicines like aspirin, and many other products like perfume and chewing gum. To these tangible aspects of the plant world we must also add the importance of beauty and relaxation derived from plants. Since animals are surrounded by and dependent upon plants, the factors that influence plant growth, structure, and distribution, affect the animal world as well.
