Question

1. Sympatric species have overlapping territory.

		True
		False, the term sympatric can only refer to evolution
		False, species never overlap in territory

2. Bees and wasps both have specialized physical and chemical defenses. Their coloration is also similar. This is an example of...

		Mullerian mimicry
		Gaussian mimicry
		Masting mimicry
		Batesian mimicry

3. Acid rain is associated with all of the following biogeochemical cycles EXCEPT...

		Carbon cycle
		Sulfur cycle
		Hydrologic cycle
		Phosphorus cycle

4. As seen in the Galapagos finch example, competition can cause character displacement.

		True
		False, character displacement has been shown to be false due to the competitive exclusion principle.
		False, character displacement only occurs with allopatric species

Answer 1

1. sympatric species have overlapping territories.

this statement is TRUE . Two related species or populations are considered sympatric when they exist in the same geographic area that is sympatric speciation occurs without a physical barrier and thus these species or populations frequently encounter one another. so we can say that sympatric species have overlapping territories and in ecology terms live in same local community such that they are close enough to interact.

2. bees and wasps both have specialised physical and chemical defences. their coloration is also similar.this is an example of-

Mullerian mimicry, because mullerian mimicry is a type of biological resemblance in which two or more unrelated organisms exhibit similar warning systems to ward of their common predators. thus having similar coloration and pysical and chemical defenses help them gaining predator"s avoidance as one harmless species adopts the appearance of another species to ward off the predator.

3. acid rain is NOT associated with PHOSPHOROUS CYCLE. as phosphorous cycle does not include a gas phase unlike carbon, sulfur, nitrogen and water cycles which inclue at least one gaseous phase of elements which makes their way in atmosphere contributing to acid rain.

4. the statement is TRUE . competition causes character displacement as seen in galapagos finches and the island dwelling anolis lizards. it is an evolutionary change when two similar species inhabit same environment and can be seen in symaptric secies.
