Answer:

The correct answer is option A) "a character that originated in an ancestor of the taxon".

Explanation:

A shared ancestral character is defined as a character that originated in an ancestor of the taxon. This type of characters contrasts with shared derived characters, which are characters that develop within the taxon and do not include all the ancestors of a given phylogenetic tree. For instance, the presence of four limbs is a shared ancestral character for a large group of animals, including amphibians, birds, mammals, turtles, crocodiles, among others.

Why do food webs consist of many predator-prey relationships?
Sindrei [870]

Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.

Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.

The cost-benefit analysis done to investigate a proposed mine site would take into consideration the cost of environmental restoration after mining and the value of the ore to be extracted from the mine.

<h3>Cost-benefit analysis</h3>

This is an analysis done to assess the cost and benefits of actions.

For an action to be profitable, the benefits must be more than the cost.

In this case, for a mine site, the value of the ore to be extracted from the mine has to be more than the cost of having to restore the site after mining.

Every other cost can also come in but the two major ones are those highlighted.
