10. (a) Explain the following terms used in ecology: (i) Niche (ii) Aquatic (iii) Flora. (b) The food web below shows the feeding relationships between some plants and animals in a woodland. Study the web and answer the questions below. (i) Name one producer from the web. (ii) Name one omnivore from the web. (iii) Name one herbivore from the web. (iv) Explain the term carnivore. (v) If there was a decline in the number of rabbits, what effect would this have on the number of foxes? (vi) Suggest two reasons why the number of rabbits might decline. (vii) What is an abiotic factor? (viii) Give one example of an abiotic factor. (c) Peacock spiders are tiny jumping spiders found in southern Australia. They do not build webs, instead they hunt small insects. They have very good eyesight and they can cover distances of up to fifty times their own length with one jump. They are called peacock spiders because of the brightly-coloured flaps the males have on their abdomens. During courtship, the male also vibrates his abdomen to attract females. Female peacock spiders are brown or beige in colour and are well camouflaged in their environment. (i) To which kingdom do peacock spiders belong? (ii) In which country are the peacock spiders found? (iii) What is the prey of the peacock spiders? (iv) Suggest two ways in which these spiders are adapted to be predators. (v) In what two ways do male peacock spiders attract females?
