Why does the loss of one species affect other species?

Answer 1

because sometimes the animal that died out is a food so if a leopard becomes extinct and that's what cheetahs eat then later on the cheetah will have no more food and die out

Answer 2

All animals are in a food chain and if 1 animal in that food chain dies or becomes extinct than it affects animals that eat it as they will have to eat other species and it affects animals that it eats because their species will grow in size. Hope that helps and makes a bit of sense!

Answer 3

the extinction of any animal affects what is known as the "food chain".

lets just say there are:

1 cat

10 birds

100 Spiders

1000 flies

basically there is an abundance of animals who are lower in the food chain. this is to feed the animals who are higher up.

(you can't have more animals higher up in the chain than lower as that would then mean the animals towards the bottom will become extinct therefore making the ones at the top die as well, whereas less animals up the top will mean the lower animals will still have a chance to reproduce to feed other animals without becoming extinct themselves.)

from my example we can see that the flies are eaten by the spiders, who are then eaten by the birds and in turn eaten by the cat.

so basically, if one animal dies, potentially all animals could die because something low in the food chain has become extinct.

And if for example the flies die, the spider will have nothing to eat, so it will starve to death, then the birds and cat will for the same reason.

however, not only can something low in the food chain becoming extinct muddle everything up, but animals high in the food chain can too.

for example, if the cat in my previous example were to become extinct then there would be way too many birds as there would be nothing to eat them, they would then require more food and that wont keep the balance of nature in order.

e.g.

0 cats

120 birds

100 spiders

1000 flies

(can anyone see the problem with this example?)

so one animal becoming extinct affects all the animals greatly, hence why everyone should work to keep the natural balance in check.

To simplify this answer, one animal species dying will cause many others to die and then when there is nothing to eat, people will die.

Answer 4

It can cause a decrease in the population of the species that use that species as a food source and an increase in the population of the species that are eaten by that species.

Example: If you have rabbits foxes and grass as three species and the rabbits all died then: The fox population would decrease due to lack of food and the grass population would increase due to lack of predation.

Seriously though dude. Open your text book. XD

Answer 5

The extinction of one organism affects another because when the it is part of the food chain. When you lose one of the organisms in the food chain, others will be affected too, because that organism was the others food. It will then either die, or adapt to a new organism to feed on.

Answer 6

If and or when the first species population plummets or becomes extinct, The second species that is supposed to consume that species will no longer be able to, thus dying off as well, so on and so forth. Or the first species produced something for another then died off, same effect happens. It's all chained up.

Answer 7

because of the interdependence of living things The extinction of one species or development of a new one often affect many others because of their interdependence in an ecosystem.

Answer 8

Because they won't be able to eat food when they're hungry and this can cause loss of nutrition

Answer 9

it causes bad things
