ENERGY FLOW AND THE FOOD CHAIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A hawk needs to eat many mice and rabbits becasue
A
there are lots of mice and rabbits in an ecosystem
B
the hawk gets only part of the energy from animals it eats
C
the hawk in a part of a large food web
Explanation: 

Detailed explanation-1: -The hawk gets energy by eating the mouse. Organisms like mushrooms also help move energy through a food chain. In this food chain, they break down material from the hawk or other organisms once they die. Some of the material becomes part of the soil that is later used by plants.

Detailed explanation-2: -Similarly, the snake will receive 100 J of energy and the hawk will get 10 J of energy.

Detailed explanation-3: -Explanation: The food chain begins with the sun: plants get their energy by photosynthesizing sunlight into energy, and then herbivores eat those plants to get their energy. Carnivores who then eat the herbivores are getting that sunlight passed along from sun to plant to herbivore to carnivore.

Detailed explanation-4: -Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.
