Food web: 1. Hawk
2. snake
3. mouse
4.grass
suppose 10,000 units of energy are available at the level of the grasses. What is the total number of energy units lost by the time the energy reaches the hawk? How did you get your answer?
(Please help me!)

GREETINGS!

10 units of energy because in food chain the energy is lost and this energy loss is 90% at each trophic level so only 10% of energy is passed soo if grass has 10000 energy units mouse will have 1000, snake will have 100 and then hawk will have only 10 units

HOPE IT HELPS YOU

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
