The population of the ground squirrels will be limited by the population of the hawks. The population of the hawks, thus, will be a limiting factor for the population of the ground squirrels. The Hawks are the birds of prey that feeds on squirrels. With the increased number of hawks in the same area as them will put these squirrels in danger. The population of the tree squirrels, however, will have no affect on the population of the ground squirrels. The genetic variability and breeding season are not limiting factors for their population either.
Hence, the correct answer is 'option B - a population of hawks'.
Answer:
A. Salamanders
Explanation:
Specialists species are species that can thrive in a unique and limited range of resources. They require a specific environmental condition to reproduce and survive in environment and also have limited or few diets they need for nutrition. These limiting characteristics put them at a disadvantage of being endangered and threatened.
Salamanders are endangered species that are fast going into extinction. They require wetland (freshwater pools) for reproduction to be possible, and feed mainly on insects. This makes them specialist species.
Ospreys, snapping turtles, and beavers are all generalist species. They can all thrive in a wide range of environmental conditions, and also have varieties of diets they can get nutrition from to survive.
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Answer:
Human activity affects the availability of food for deer populations in many ways. Hundreds of years ago, dear were very rare but now more civilization has occurred making more food for dear in the gardens outside of peoples houses. Also, people have started to kill organisms that they found harmful to themselves, causing the dear population not to decrease, but stay the same and reproduce.
