(i) Biodegradable substances are decomposed by the action of microorganisms and decomposed materials are recycled through geo-chemical cycle. (ii) These substances keep the environment clean.

The main reason of a substance being biodegradable is being organic that can be used up by scavengers of environment. On the other hand some substances are non biodegradable because they are synthetic and cannot be decomposed by the microorganism.

Some approaches towards the conservation of forests are: 1. Conversion of forests into national parks, sanctuaries. 2. To take help of local people in conserving forest. 3. Not to allow the destruction of forests for making roads, dams and hotels etc. 4. Planting of trees should be increased.

We should conserve forests because they are essential for us in the following terms: 1. Forest provide us with oxygen, they cause rainfall. 2. Forest prevents soil erosion. 3. Plants are dependent on animals and birds for their pollination and seed dispersal. 4. Forests provide us with various medicRead more

The purpose of reflex action is to provide quick response in situations where the organism does not have enough time to think. Reflex arcs are formed in the spinal cord, although the information inputs also reach the brain. This helps the brain to record this event and remember it for future use.

Give any two ways in which biodegradable substances would affect the environment.
(i) Biodegradable substances are decomposed by the action of microorganisms and decomposed materials are recycled through geo-chemical cycle. (ii) These substances keep the environment clean.

Why are some substances biodegradable and some non-biodegradable?
The main reason of a substance being biodegradable is being organic that can be used up by scavengers of environment. On the other hand some substances are non biodegradable because they are synthetic and cannot be decomposed by the microorganism.

What is the role of the brain in reflex action?
The purpose of reflex action is to provide quick response in situations where the organism does not have enough time to think. Reflex arcs are formed in the spinal cord, although the information inputs also reach the brain. This helps the brain to record this event and remember it for future use.
