a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?

Answers

Answer:

hunting, the predator is in the middle of the food chain

Explanation:

hunting can WIPE OUT species as shown by the dodo bird in the past.

food chains often work as 1-2-3 or 1-2-3-4 in levels.

A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

What happens if in a particular food web a new prey animals are introduced?

If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.

Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.

Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

I thought Resilient because the rainforest has changed over time because it was fragile before.

Answers

If 4 grams of water vapor are present in a cubic meter of air that can hold a maximum of 10 grams, what is the relative humidity?

Answers

Answer:

40%

Explanation:

The relative humidity refers to the ratio of water vapor present in the air and the maximum amount of water vapor that the air can hold at a given temperature.

Mathematically, it can be expressed as;

Relative humidity = amount of water vapor in the air/maximum amount of water vapor the air can hold x 100%

In this case,

Amount of water vapor in the air = 4 grams

Maximum amount of water vapor the air can hold = 10 grams

Relative humidity = 4/10 x 100%

                               = 40%

Hence, the relative humidity is 40%.

What is the benefit of using sunscreen when working outside every day?

Answers

Answer:

Not only does it protect from UV rays, it also works to reduce the appearance of pores and fine lines over time, so you're actually improving your skin while wearing it.

Explanation:

Answer:

It prevents cancer.

Explanation:

UV rays penetrate the many layers of the epidermis, reaching the deep layers of our skin, which is meant to be protected. This activates pigment cells, releasing Melanin and darkening the skin.

When the UV rays penetrate these deep cells, it reacts similarly to radiation, denaturing and breaking apart DNA. If enough damage is done and the cell becomes irreparable a tumor forms.

Consistent exposure to UV rays has detrimental effects because it puts your skin cells through this same stress every day.
