Question

How do plants and animals get their energy in different ways?

Answer 1

Hint: Plants produce their energy by themselves but animals are dependent on the plants for their energy and cannot produce energy by themselves.

Complete answer:
1)Mostly the plants are producers, which means they are capable of converting the sunlight that is the solar energy into chemical energy. The entire process of this energy conversion is known as photosynthesis. During photosynthesis, the green plants use the raw materials in the presence of sunlight, and the products formed are mainly glucose and water. This glucose then undergoes cellular respiration which leads to the formation of pyruvate and ATP. The ATP is the source of energy for the plants.

2)Whereas the animals do not undergo photosynthesis or any similar process. The animals are dependent on the plants for obtaining energy as they cannot directly obtain energy from sunlight. The animals can directly feed on the plants or they can feed on other organisms that were dependent on the plants for their nutrition.

Note: The highest amount of energy is possessed by the green plants because they are producers of energy and hence they form the base of the energy pyramid and they form the first trophic level of the energy pyramid and the plants supply energy directly or indirectly to other organisms that are primary consumers, secondary consumers and the other trophic levels of the energy pyramid.
