Question

A nonnative species of animal is introduced into a healthy ecosystem. In its new environment, this species has no predators, although it preys on several native animals in the ecosystem. Make a prediction about the biodiversity and health of this ecosystem in the future.

1. Biodiversity and ecosystem health will both increase in the future.
2. Biodiversity and ecosystem health will both decrease in the future (I THINK THIS ONE)
3. Biodiversity will decrease and ecosystem health will increase in the future.
4. Biodiversity will increase and ecosystem health will decrease in the future.

Answer 1

@bibby can you help me?

Answer 2

sounds about right. with nothing controlling it's population itll consume more prey ultimately decreasing biodiversity.

Answer 3

its* it'll*

Answer 4

Thank you! Can you help me with one other question?

Answer 5

possibly. I haven't taken bio since 9th grade (like 7-8 years ago now) so I"m pretty much just making educated guesses FYI

Answer 6

Ok here's the question:
Adult birds of one species hatched eggs of another species along with their own eggs, and raised all of the babies together. The foster chicks use a different warning cry than the other chicks. What can you infer about this warning cry?
1. It results from instinct
2. It results from imprinting
3. it results from trial-and-error learning
4. it results from conditioning

Answer 7

I think it's number 2 but can you help?

Answer 8

I think it's either 2 or 4

Answer 9

it's probably not 3 or 4, I'm reading up on the difference between instinct and imprinting. If the mother is supposed to be teaching the baby, then I don't think it's imprinting either

Answer 10

Ok so it's 1 then?

Answer 11

I'm going to go with 1 after reading this https://ninjajacoblogy.wordpress.com/2012/05/03/animal-behavior-imprinting-fixed-action-patterns/

Answer 12

Ok I think it makes more sense now. Thank you!
