chapter reviewQ3. A) The important a-biotic and biotic features of the dusky horseshoebat are.An a-biotic feature is the cave or the level of light, and a biotic featureof the dusky horseshoe bats habitat is the other bats living in the caveand the insects that they are feeding on.

B) Two actions that could lead to the destruction of the dusky horseshoebat are,If all the insects were sprayed so that there were fewer insects for thebats to survive and therefore the bats habitat would be destroyed. Andthere was sum sort of natural disaster and the cave fell in the bats homewould be non-existent and they would have to find another home.C) In the order of protecting the dusky horseshoe bat I would ban the useof chemical and natural pesticides and make the bats home a protected areaput up fences so that no ferial animals can get in to the caves and killits inhabitants.Q4. If I was given the task of making a habitat for a terrestrial mammalfor it to successfully breed and live it would make the habitat mimic itsoriginal habitat where they are found, but make a few things better likemake the food scores more available but make it interesting for the animallike its hunting in the wild, and make more nesting and shelter sites, Iwould also put a lot of indigenous shrubs and plants from the area that theanimal was caught from and then eventually bring in another animal of thesame type and try and make them breed.Q5.

A) In the areas that the pygmy possum lives in there is a large breakin its range.B) In the area where there are no pygmy possums live there must be anatural feature or a shortage of food that the possum will need to survivein that area or predators may be in abundance in that area or there is tomuch pollutants in that area where the pygmy possum is not found.C) You could travel the whole way through the range of the western graykangaroo and not see one, but it is most likely that you will see one. Ananimal might have a large range in which it lives in but the population ofanimals in that area might be small to nothing.

Q6. A) All the birds in question 6 share the same habitat.B) All the birds in question 6 all feed at different places on a tree sothat there is no competition for food one feeds at the top half of thetrunk and another feeds at the lower half of the trunk and another feedsbuy stripping off the bark from the branches and another feeds at theleaves. No competition.

C) The bell miner’s niche is to eat the insects form the leaves and thecrested shrikes niche is to eat the insects living in the bark off the treetrunk the separation between these two birds is that they use differentparts of the tree and are designed to get food in a different manner.D) In the lower part of the tree the crevasses might be bigger and easerfor theVaried sitellas to collect their food and up higher up the tree thecrevasses might be smaller so the varied sitellas cant get to them, ortheir might be a preferred food score at the bottom of the tree for thevaried sitellas.Q7. A) The variables in the graph on page 123 are the temperature and thetime.

B) 1. The approximate temperature in the cushion of vegetation at noon is29 degrease.2. The approximate temperature of the air at noon 6 degrease.

c) Yes it dose if the trees did not drop their leaves the ground would notbe covered in the thick layer of vegetation this makes a humid environment.Q8. A) The velvet sea star and common sea star do not occupy the same nichebecause they are only some times found in the same spots as each other andmost of the time theThe velvet sea star and common sea star occupy different depth of wateronly some times do their habitats cross over.

B) The firebrick sea star and the velvet sea star will not displace oneanother because one occupies the water between 20 and 400m and the otheronly in 30m and the firebrick sea star also feeds on detritus.C) …Q9. A) The chest nut teal ducks and the black swans both eat the same foodbut the chest nut teal duck feeds in the shallows on the vegetation on thebottom of the lake and the black swan feeds in the deeper parts on thevegetation from the bottom of the lakeSo this means that the 2 birds can survive in the one place together.B) Both animals feed from different parts of the lake so that there is nocompetition from the other species.

C) Both birds feed in different manners and in different water depths, theAustralian pelican feeds scooping its bill in the deep water for small fishand the white faced herons feed buy thrusting their beaks at the small fishin the shallow water.D) One animal takes the insects out of the air and the other takes theinsects in the reeds around the lake. So they are not in competition forfood.

E) The pink eared ducks feed on small plants and animals buy filteringwater thought their bills on the water surface, and the maned ducks feed onvegetation in grassy areas around the lake, and the musk ducks dive downand feed on small organisms near the lake bottom. So all three of theseducks could all live together in the one place and none of them would beunder competition for food.F) The sand piper would have a long beak with a large rounded area at thebottom of the beak to search a larger area of the lake bottom, and thewhite-faced heron would have a long pointed beak for catching fast movingfish.

So both beaks are different for 2 different purposes.
