I encountered a similar question with these give choices:

<span>A) Mass and energy are conserved in the carbon cycle.
 B) When all the fossil fuels are used up, there will be no more carbon.
 C) As population sizes increase, more carbon is produced.
 D) The Sun absorbs energy from the carbon cycle.

Among the choices, only choice A is the true statement.

Mass and energy are conserved in the carbon cycle. This is known as the Law of Conservation of Energy and Law of Conservation of Mass. 

Mass and energy remains constant. They are neither created nor destroyed. They simply are recycled and take on different forms but are of the same measure.</span>

Describe the trophic structure of energy in an ecosystem
ale4655 [162]
As you go up in an ecosystem the bigger animals have less energy. While the organisms down at the bottom like plants that create their own energy have greater amounts. This is because energy is rated doing everyday things. As energy travels up the food pyramid, it looses more and more energy. This is knower as the 10% rule. In which every time you go up 10% of energy is lost.

Why dominant traits may not necssairly be more common in a population
nataly862011 [7]
This isn't always the case and there is no reason it should be .Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive. Let's take eye color as an example.

3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
katen-ka-za [31]

Answer:

The plants have the higher population density. This is because, when compared with that of the insects, the number of plant species per acre area is higher; 2800 compared to 683.3

Explanation:

The number of individual species per unit area of land is known as the population density. Population density describes how crowded or spaced out a given species is in a particular area. The higher the population density, the more crowded the species are and vice versa. The formula for calculating population density is given as:

Population density = Number of species/land area

Population density of the insects = 820/1.2 = 683.3 insects/acre

Population density of the plants = 560/0.2 = 2800 plants/acre

Therefore, the plants have the higher population density.

This is because, when compared with that of the insects, the number of plant species per acre area is higher.
