For once, it would be a good thing to see a species decline a bit. The adaptable coyote is found now in great numbers where it is not native, and has become a threat to native species and livestock, even children.
Birds have greatly reduced in number due to human activities which lead to dwindling habitats for the birds. Some birds are also often hunted by many predators hence making them reduce in number.
Biologists estimate extinction rates in a great number of ways. One way is to document the decrease in population over time.
The hare's population would decrease if the number of predators that eat the hare increased. Take the Lynx for example. In 1865, The population of hares in the forest was almost over 150. But 1 week later, the population dropped by 50 due to more lynxes in the forest. Another reason might be because of migration. Migration might have happened because the hares were simply frightened. Hoped this helped :D
Well, the population of the fish being taken will decrease, prehaps becoming extinct. The food web will be damaged as well.
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.
the plankton population would decrease
the plankton population would decrease
the plankton population would decrease
If the owl population increases, the vole population will decrease. This is because there will not be enough voles for all of the owls. Then the owl population will decrease, therefore causing another increase in vole population.
A sudden decrease in the butterfly population would cause a corresponding decrease in the chameleon population since they no longer have enough food.
If the number of phytoplankton decrease the food chain would decrease in the ocean.
the bears would decrease because bears eat salmon
they grow... THE FOOD CHAIN GOES DOWN FAST though
decrease;males as they age
population pyramid;decrease (apex)
there would be less nutrients for the plant.
The number of first level consumers would decrease causing the second level to also decrease and so on up the food chain.
