Answer:

The correct answer is C) foundation species

Explanation:

Foundation species are species who play a great role in creating a suitable habitat and maintaining that habitat that supports the living of a community with many different species.

They are also referred to as ecosystem engineers because they are able to create and modify a new habitat that affects the lives of many species. Some of the examples of foundation species are earthworms, beavers, corals.

Beavers are famous foundation species that transform their environment from streams to ponds by making dams that support living of other animals like some fish species like trout, many plant species, amphibians, and birds.

Therefore the correct answer is C) foundation species.

Under what conditions does the trp repressor block transcription of the trp operon? (A) when the repressor binds to the inducer
Brilliant_brown [7]

The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.

trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.

Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.

Describe the energy pyramid describe the biomass pyramid
kogti [31]
The energy pyramid describes decomposers compared to energy lost as heat. Primary producers start at 100% and it decreases to 10% at primary consumers, 1% at secondary, .1% at third level, and .01% at apex.
The biomass pyramid describes the total mass of an organism and as a biomass moves up, the overall mass is losing volume. This means it decreases as it moves from the bottom to the top.
