Answer 1

31. C) Mutualism

It is a kind of symbiotic relationship where both are benefiting each other. The sea anemone offers clownfish protection and leftover food.

32.C) TLTE is highest when the primary production rate is also highest.

This is because the source represents the sun and primary producers represents the plants

33. D)spatial learning in animals

It is an experiment conducted to study animal behavior in its natural environment.

34. D)9 Exploitative competition

This happens due to seasonal variation
