Explanation / Answer
Answer 1(c) type 3 survivorship curve has a low survival of young ones but once they survive they thrive well e.g. marine animals.
Answer 2(d) equilibrium, where a stable state is maintained throughout.
Answer 3(d). stochasticity
Answer 4(a) co-variance
Answer 5(a) paradox of enrichment
Answer 6(C) Parasitoidism is a relationship where a parasite kills its host. eg. wasps
Answer 7 Resources are distributed unevenly in clumped distribution. the populations are closely maintained around the patchy resources.
