Most energy enters ecosystems in the form of sunlight. select the best answer from the choices provided t f

Answer : The given statement is True.

Sunlight is considered as the major source of energy for all living organisms present on earth.

Energy from sunlight (solar energy) is used by green plants and algae to synthesise their own food through a process called photosynthesis.

The food is consumed by different organisms that lie at different  trophic levels in the food chain within an ecosystem.

Thus, the ultimate energy source for the life forms is sunlight.

Therefore, given statement is True.

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.
