How does deforestation contributes to the increase in numbers of endangered species?
it destroys their habitats
How does a predator increase numbers of species in an ecosystem?
When a predator reduces the number of one species in a habitat, the population of competing species can increase. With less competition for food, water, and shelter, a species can thrive and reproduce more rapidly than when it is being out-competed.
When numbers of a species begin to decline?
If the numbers of a species begin to decline dramatically, the species becomes known as an "endangered" species. When the numbers decline so far that the species no longer exists, the species is known to be "extinct."
What is a species if its organisms are found in very small numbers?
If a species is endangered, the organism will be found in very small numbers.
What is an enndangered species?
a species whose numbers are so small that the species is at risk of extinction
Are crocadiels endangerd?
There are several different species of crocodile, the estuarine or salt water croc, have seen their numbers increase over the last 30 years or so due to several breeding programs. However, other species do not fare so well and numbers are reducing. Habitat loss to human beings is a large factor in this.
What happens it the food chain when you over fish?
When over-fishing of a species in a food chain occurs, this would the species which eats the over-fished fish would reduce in numbers due to less food and species which the fish ate would increase in numbers due to less predators. This effect continues through the food chain, eg if Krill was over-fished, Whales would decrease in numbers because there are less food for them. Anything that eats whales as their main prey would also decrease in numbers due to less food. Krill eats a type of plankton. They would increase in numbers because of less predators. Plankton eat phytoplankton, since there are large numbers of plankton, the phytoplankton would decrease in numbers. Overall, over fishing would cause the food chain/web to become unstable
How are a population and community different?
A population biologist studies the number(s) of species as they increase or decline in relation to their density or some environmental factor. Community ecologists study the numbers and interactions of all the species in a given location.
Can mutations increase the variations in a species' traits?
Yes
When have the greatest numbers of the species pouplation?
Insects.
What does endgered mean?
A species whose numbers are so small that the species is at a risk of extinction.
Which of these choices is a sign that a species' numbers are declining?
It has been placed on the list of endangered species.
