A big environmental problem is the destruction of habitats of many animals and plants due to mining, deforestation or other actions caused by human interventions. Ecology can determine what level of human intervention can be tolerated and how much interaction is “too much”.
Molecular ecology can be defined as an area of evolutionary biology which examines the dynamics of ecology on a molecular level.
The ecological pyramid describes biomass productivity in a given ecosystem at each trophic level.
The science of ecology is important since it raises the awareness of people on our ecological problems and how to solve them.
The ecological footprint measures the human impact on our planet’s ecosystem.
Primary succession describes the stage in the ecological succession where organisms colonize an area that has previously hit by a natural disaster that wiped out all life in this area.
Protection of our climate. Since ecology examines the interactions of different organisms, it can also study how climate change affects ecosystems. Thus, ecology can help to understand the adverse effects of global warming and can also give indications on how to mitigate the climate change issue.
E) water pears and fig trees that extract nutrients from the springwater through their roots.
A) Forest fires did not occur in the times before human settlement.
E) Fire is not an important factor in developing and maintaining ecosystems.
Unfortunately, soil type and depth can widely vary across a golf course. Fertilizer is used as a supplement to improve turf health and den sity where the soil alone is not meeting the plant’s needs. Areas of the course that have infertile, shallow or sandy soils, or experience heavy golfer traffic, are examples of locations that often require supplemental nutrition to achieve the desired turf quality.
Fertilizer should not be applied to produce a vibrant green color, but rather to encourage healthy turf that can recover from environmental stresses as well as golfer and maintenance traffic.
It is especially important to avoid excess fertilization in the rough immediately adjacent to the fairways to avoid penalizing slightly missed golf shots. Applying the right fertilizer source at the proper rate and at the appropriate time is an important balancing act required to prevent overfeeding. A golf course does not need to be wall-to-wall green to offer enjoyable, high-quality playing conditions.
Adding fertilizer to plants that are already healthy can negatively impact playability and increase maintenance costs because excessive growth requires additional mowing and clippings cleanup.

There is a good opportunity for golfers to make a clean strike on the ball sitting on short, thin turf. Excessive growth likely will come between the club face and the ball, reducing both distance and spin.
But, there can be a downside. When we overapply fertilizers – no matter whether they are natural ones like manure or synthetic fertilizers – excess nutrients are washed off and pollute the natural environment.
Their crop yields suffer as a result. This is bad for farmers; food security; and the environment because it means they need to use more land for agriculture. As I covered in my recent article, Sub-Saharan Africa is projected to be the hotspot of habitat loss in the coming decades as a result of expanding croplands. Thousands of mammals, birds and amphibian species are at risk. The good news is that if we can improve crop yields, we can prevent almost all of this. Fertilizers will play an important role in achieving this.
Nitrogen and phosphorus are the two main fertilizers that farmers add to their fields. Research presented here shows that nearly two-thirds of the nitrogen we use on our crops becomes a pollutant; more than half of applied phosphorus does. There are large differences in how much pollution countries generate through their agricultural practices. Some produce almost none; others produce hundreds of kilograms per hectare of cropland.
But total excess is also important because it informs us of where we’re likely to have hotspots of water and ecosystem pollution. We need to be aware of regions with lots of farmland and excess nutrients because surrounding rivers and lakes are at high risk of becoming polluted.
This happens when countries undersupply nitrogen fertilizers, but continue to try to grow more and more crops. Crops then have to take nitrogen from the soil. Over time this depletes soils of their nutrients which will be bad for the productivity of these soils and crop production in the long-run.
We can measure this using a metric called “ excess nutrients”. This metric shows us how much of the nutrients that farmers apply as fertilizer runs off into the natural environment.
Fertilizers have brought the world massive socioeconomic and developmental benefits. They improve crop yield s. This has two advantages. First, we can grow more food. Second, we need to use less land for farming, and therefore destroy fewer ecosystems in the process.
