The first step in the food chain is always

	a sesame seed bun
	a producer
	sunlight

Most first order consumers are

	autotrophs
	herbivores
	carnivores

If a dog and a wolf eat the same thing, and live in the same area, they might be

	neighbours
	key stone species
	competitors

If two animals live in close connection each other, their relationship is a form of

	symbiosis
	food web
	biological magnification

In a symbiotic relationship, if one animal suffers, but the other thrives it’s

	a predator / prey relationship
	commensalism
	a competitive relationship

If a keystone species is removed from its environment

	what’s a keystone species?
	nothing changes
	the environment changes completely

With parasitism

	one species gains, the other suffers
	both species gain
	one species gains, the other is unaffected

An example of mutualism is

	cow egrets and cattle
	myxomatosis and rabbits
	good gut bacteria and it’s host

Biological magnification is the

	investigation of micro organisms under the microscope
	concentration of chemicals and heavy metals up through the trophic levels
	the regeneration and expansion of the natural environment into farmland

Another name for scavengers is

	recycler organisms
	detritivores
	detritus

Producers are always

	autotrophs
	on the first trophic level
	both 1 & 2

Amensalism could be a way of describing

	the relationship between cattle and rabbits
	the way people treat the world
	the relationship between horses and gumtrees

Parasitoids are often insects, which

	lay their eggs on hosts for their larvae to feed off of
	only inhabit the gut of their hosts, living off of their stomach contents
	have larvae that eat leaves

Farmers dislike rabbits because

	they are hard to catch when you want some stew
	they compete with livestock for food
	their horses trip on the rabbit holes

The last step in the food chain is most likely to be

	a third order consumer
	a producer
	a detritivore
