Answer:

The ecosystem would collapse if producers were removed.

Explanation:

The primary consumers populating would decrease due to lack of food and if a species doesn’t have food they most likely won’t reproduce. The secondary consumers won’t have enough food either because their prey being the primary consumers would die off. All this leads to the down fall of ecosystem.

IceJOKER [234]

The correct answer is pharyngeal pouches.

All chordates for at least some period of their life have pharyngeal pouches (pharyngeal slits). Those are the openings in the pharynx with the function in the filter-feeding.

You are given two true-breeding groups of gerbils. The gerbils in the first group have black fur and curly tails; the gerbils in

Alexxx [7]

Answer:

3 black gebrils have straight tails

Explanation:

Given -

First group of true breeding gebrils have black fur and curly tails

Second group of true breeding gebrils have yellow fur and straight tails

After the F1 generation, all the offspring would have black fur and curly tail

This means black fur is dominant over yellow fur and curly tail is dominant over straight tails

Let "Black fur" be represented by "B" and "yellow fur" be represented by "b"

Let curly tail be represented by "C" and straight tail be represented by "c"

Then parents genotype for F1 generation would be "BBCC" and "bbcc"

and genotype of first generation offspring would be "BbCc"

BbCc
