Q1 WHICH ARE BIODEGRADABLE MATERIALS?
a) ALUMINIUM WIRE
b)TEA LEAVES
c)SYNTHETIC FIBRE
d)WOOL
e)AGRICULTURE RESIDUE
f)PLASTIC
g)INSECTICIDES
The biodegradable materials are; Tea leaves, Wool, and agricultural residue.Meaning that they can be decomposed in the environment by microorganisms.
The rest are non biodegradable. Meaning that they cannot be decomposed in the environment.
Q2 IN A FOOD CHAIN CONSISTING OF GRASS, FROG, BIRD AND INSECTS, WHERE WILL CONCENTRATION OF HARMFUL CHEMICALS BE MAXIMUM?
In a food chain, organisms found in the levels of the food chain usually tend to have the highest levels of toxic substance accumulated in their bodies.
This occurrence is majorly due to bioamplification also known as biological magnification or just biomagnification.
Biological magnification can be defined as the increase in concentration of substances, especially toxic chemical substances in the tissues of organisms and at successively higher levels of the food chain.
In this food chain we have been given, the bird is at the top of the food chain and is likely to be the organism with the highest accumulation of toxic substance in its body.( grass---->insect---->frog---->bird)
Q3 ARRANGE IN FOOD CHAIN FISH, ALGAE, SMALL ANIMALS, BIG ANIMALS
Algae → Fish → Small animals → Big animals

Answer:
Q.2 Bird
Explanation:
Beacause we know that concentration of chemical increases as we go to higher tropic level and here, in this food chain bird is top carnivore animal, in 4th trophic level as a tertiary consumer. so, Bird is the correct answer
Q.3 ALGAE ---》FISH ---》 SMALL ANIMAL ---》 LARGE ANIMAL
