5. What would you do to help maintain the
equilibrium in the various bio-geo-
-chemical cycles? Explain in brief.
Explain in detail the inter-relationship
between the food chain and food
web.
7. State the different types of bio-geo-
chemical cycles and explain the
imnortance of those cycles.
Answers
Explanation:
An ecosystem balances itself out in a number of ways. This dynamic equilibrium that it must maintain is known as homeostasis. One way that an ecosystem obtains and keeps a balance is through predation.
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food webshows the many different paths plants and animals are connected.
Biogeochemical cycles serve a variety of functions at ecosystem level and in ensuring survival of various organisms including humans. Below are some of the importances of biogeochemical cycles. Biogeochemical cycles enable the transformation of matter from one form to another.
Explanation:
i. Human activities on the large scale such as clearing forest or cutting of trees on large scale (deforestation), burning of fossil fuels, more use of chemical fertilizers, and pesticides.
ii. These activities disturb the biogeochemical processes, directly or indirectly.
iii. Some steps should be taken to maintain the biogeochemical equilibrium in the ecosystem such as:
1. Plant more and more trees to maintain oxygen and carbon dioxide balance in nature.
2. Least use of chlorofluorocarbons.
3. Reduce vehicular pollution.
