Answer 1

1. Renewable resources can never be exhausted. Natural resources diminish with time.

EXAMPLES

(1) 1. These resources are renewed or replenished by nature in a short period These resources may not be replenished by nature or take a very long geological time to be formed again.

(1) 2. Often these are available continuously like solar energy water etc. These resources are exhausted after the use of Ex-fossils etc.

(1) 3. Renewable resources can be divided into continuous or flow Non-renewable resources can be recyclable or non-recyclable

2. It may lack natural predators or controls. It may swiftly reproduce and spread, taking over an area.

3. If the producers were removed, the food chain would have no beginning and the entire ecosystem would perish. There would be no organic nutrients and all the dead plants would destroy the animals' environment if the detrivores and decomposers were gone. Because there would be no breakdown of waste, the environment will be filled with plant and animal waste.
