Question

How do plants get food?

Answer 1

Hint: Plants are producers and are autotrophic and are not dependent on any other organisms for their food. Mostly the plants are producers, which means they are capable of converting the sunlight that is the solar energy into chemical energy.

Complete answer:
1)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)Producers obtain their energy directly from solar energy but other organisms are dependent on these producers for obtaining energy. Glucose and starch are the main foods required by the plants. Also, plants can directly absorb minerals and nutrients from the soil with the help of roots. Vascular bundles that are xylem and phloem helps in the transportation of food, water, and minerals to different parts of the plant.

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