Ecology is the study of environment and biology is study of plant and animals.The interrelationship between an organism and environment

Explanation:

Ecology is the study of organisms, its distribution, abundance,interrelationship with another organism and the interaction of organisms with their environment in which they adapt to survive.

Sunlight is the main source of energy for living beings on earth. Movement of energy flow and nutrient cycle plays a significant role in living beings.

In ecology there are different levels of organization such as species,  population community,ecosystem,biome and biosphere.

There are different cycles which an organism required to survive, carbon cycle, nitrogen cycle, oxygen cycle, phosphorous cycle, and of course the most basic thing to survive is the water cycle. All these cycles coming under one term called the biogeochemical cycle.

The ecological pyramids such as pyramids of an ecosystem, pyramids of number pyramids of energy flow and pyramids of biomass based on these pyramids living things survive.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
