consequence of decreased biodiversity in coral reefs?


A. More niche opportunities for land species


B. Increased number of predatory species


C. Increased stability of all other biomes


D. Less seafood in the human food supply

Answers

Answer:

D

Explanation:

A is wrong, it's talking about land. B is an increase in biodiversity. C is wrong because other biomes depend on reefs

The one consequence of decreased biodiversity in coral reefs can be increased number of predatory species. The correct option is B.

What are predatory species?

Predatory animals are those that kill and then eat other animals, or "prey on" them. Predatory animals include hawks, lions, alligators, and humans. When one party victimizes another for personal gain, the term predator is also used.

Predation is a natural feeding behavior of animals, plants, and microorganisms in which one species feeds on another for survival. Predation is the process by which one animal kills another and consumes it as food.

Increased predatory species may be one of the consequences of decreased biodiversity in coral reefs.

Fish, marine worms, barnacles, crabs, snails, and sea stars are all predators of coral polyps' soft inner tissues. In extreme cases, large predator populations can devastate entire reefs.

Thus, the correct option is B.

In a population of wolves, the birth rate is 4, the death rate is 3, immigration is 2, and emigration is 3. Calculate the population growth by filling in the formula below. ( + ) – ( + ) = Since the population growth is , the population is

Answers

Basically there will only be 2 wolves that survive in the end. The wolve that gave birth and one baby because theoretically in this situation 3 die and immigration and emigration don’t mean anything.

Population growth is defined as an increase in the number of individuals in a population. Thus, the population growth in the above example is zero.

What is Population growth?

Population growth is defined as an increase in the number of people in a population or a dispersed group. Population growth is explained as an increase in the number of individuals in a population.

Population growth is defined as an increase in the number of individuals in a population where most communities with high population growth experience limited resources, for example food, while communities with low rates of population growth do not.

This formula is used to find out the population growth of a population; (Birth rate + emigration) – (death rate + emigration).

Given,

Birth rate = 4, the death rate = 3, immigration = 2, and emigration = 3.

Population growth = Birth rate + immigration - death rate -emigration  

= 4 + 2 - 3 - 3

= 6 - 6

= 0.

Thus, the population growth in the above example is zero.

Since the 1970’s, the Earth has been warming. Can this be due to natural, increased solar output? Why or why not?

Answers

No.

The Sun can influence the Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. We know subtle changes in the Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.
