Please answer it seriously! Thank you in advance!! In every ecosystem, energy is transferred along food chains from one (1) to the next. Every time energy is transferred, only (2) is absorbed by the next consumer. Therefore, the longer the food chain is, the (3) amount of energy is received by the last order consumer. The number of population of organisms can be affected whenever there are changes in the number of population of other organisms. Such changes are caused by (4) such as hunting, pollution, mining and deforestation. There will be (5) in population if the food source is limited. In a forest ecosystem for example, (6) may lead to loss of habitat of (7) . Aside from human interference, changes in abiotic components of an ecosystem may also affect the number of population. In cases of drought, the supply of (8) is limited affecting the growth of plants which serves as (9) in the ecosystem. Consumers who depends on plants for food are also affected. Since man is the primary cause of imbalance in the ecosystem, it is important that man must be responsible for its restoration. One way of maintaining balance is to (10) it.
