Answer:
C. It uses a renewable resources
Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.
"Mechanical Energy is the energy of motion of an object"

<u>Answer:- </u> Decomposition
<u>Explanation:- </u>
Decomposition is a natural process that occurs in the environment to break down organic substances into simpler substances.
- All the living organisms that die, are decomposed and their bodies are broken down into simpler substances such that the nutrients are released into the soil.
- The plants are then able to absorb these nutrients from the soil and thus, the nutrient cycling goes on as the organisms feeds on it.
- Not only the dead animals but also the fallen leaves and other parts of the plant gets decomposed as they die.
- The process of decomposition is carried out by living organisms present in the soil such as bacteria. Such organisms are called as decomposers.
