Answer:

1,000 kcal

Explanation:

As a general rule, every trophic level only gains 10% of the energy from the trophic level.

So, the grass has 100,000 kcal of energy.  Assuming the bird eats grass, it only gets 10,000 kcal of energy.  Assuming the fox eats the bird, it only gains 1,000 kcal of energy.

Keystone predators can maintain species diversity in a community if they _________. A. competitively exclude other predators B.
Alisiya [41]

Keystone predators can maintain species diversity in a community if they  prey on the community's dominant species

Option B is correct.

A keystone species is usually a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. other forms of keystone species are those, like coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.

Are keystone species always predators?

A keystone species is usually , but not always, a predator. Just some predators can control the distribution and population of large numbers of prey species. the whole concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.

Explain why habitats with high biodiversity tends to contain narrow ecological niches and white habitats?
alexdok [17]

Answer:

because they reduce interspecific competition

Explanation:

Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.

Which choice below best shows various types of genetic material in order from simplest to most complex? genome chromosome gene g
Kisachek [45]
The chromosome is the one that carries the genetic information. The gene is the basic unit of heredity, meaning, this is the one that we carry from our parents. Genome is the collection of genes that is present in an organism. Therefore, if we arrange this from simplest to the most complex, the arrangement would be GENE, CHROMOSOME, GENOME.
