When can antlions experience competition

2 answers:

Antlions experience competition when there is a scarcity of food and few spaces to burrow in the sand. This happens during their larval stage when there is an overlap on their reproduction where the large ones consume the small ones for survival.

<h2>Answer: </h2>

It happens when there is extreme scarcity of the food items.

<h2>Explanation: </h2>

This would happening to take place as during the course of the larval stage at the time when there is an overlapping set of the reproduction. This is all possible at the time when the large ones are in consumption with the small set of the survivals.

Answer:

Speciation results in biodiversity.

Explanation:

This phylogenic tree shows the changes in bacterial species from the ancestral species to the most current split in the modern classification system. This tree supports the theory that <u>speciation results in biodiversity</u>. As we know speciation is the terminal source of the latest species, in a similar way, that modification is the terminal source of genetic divergence within species (and extirpation is comparable to lack of alleles). Inequities in the movements of speciation are therefore expected to provide large scale biodiversity exemplars.

Stells [14]

A person does have basic human rights and one is the freedom of expression. Though this is the case, we should understand that our right to freely express ourselves (from political to religious views), it does not necessarily give us the right to impede another person’s. A play with words can easily hurt or even harass other people, and in return may be a form of human right violation.

In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,2

Alisiya [41]

Answer:

Suppose that we have a given function f(x)

The average rate of change of the function between two values x₁ and x₂ is given by:

$r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}$

a) We want to find the average (rate) of change on the size of population from 1985 to 1995.

We have that:

f(1985) = 750

f(1995) = 1500

Then we have:

$r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75$

This means that the population of trees increases, in average, at a rate of 75 trees per year.

b) What is the density of trees each year that they were counted?

This will be equal to the quotient between the number of trees and the area.

1985: number of trees = 750 pines

area = 250 ha

Then the density is:

D(1985) = (750 pines)/(250 ha) = 3 pines/ha

So 1985, there were 3 pines per hectare.

1990: number of trees = 1250 pines

area = 250 ha

Then the density is:

D(1990) = (1250 pines)/(250 ha) = 5 pines/ha

1995: number of trees = 1500 pines

area = 250 ha

The density is:

D(1995) = (1500 pines)/(250 ha) = 6 pines/ha

3) now we want to get the average change between 1985 and 1995 in the density, this will be:

$r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha$

So, on average, each year the number of pines per hectare increases by 0.3
