emmainna [20.7K]

Answer:

1,250,000 shrimps per m³

Explanation:

Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;

Population density = population (N)/volume

According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;

Population density of the lake = population of shrimps ÷ volume of lake

Population density = 600,000,000 ÷ 480

Population density = 1,250,000 shrimps per m³

What conditions are possible reasons for declining genetic diversity of a species? Select all correct answers.
yan [13]

Some conditions that are possible reasons for declining genetic diversity of a species;

▪︎loss of habitat

▪︎inbreeding

Explanation:

Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.

Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.

Describe how you are involved in both the carbon and oxygen cycles
iragen [17]

Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings.
