Explain how predator and prey populations limit each other growth rates.

Notice that independently, the prey population goes up, if the predator's population is low. One interpretation is that there are not enough predators to really make a dent in the prey's population. But as the prey's population increases, they become easier targets for the predators since there are so many. As predators feed on prey, the predator's population increases (more food, can sustain a bigger population) and the prey's population decreases. As less and less prey are available to hunt, the predator's population also decreases.

Note that it need not be this cyclical, the trend can go to an equilibrium point where the populations do not fluctuate all that much.

the predator eats the prey limiting them to not overly grow. And the prey do not overly grow limiting the predators population to not overly grow as well. hope that helps

The predators feed on the prey population leading to their increased mortality rates. As a result, there will be less prey for the comparatively larger predator population. Therefore, due to the scarcity of food resources (prey) the growth rate of the predators would also be lowered.

Further Explanation:

When one species hunt on another species for food, the hunting species is called a predator while the other species to be fed on is called the prey. This is called predator-prey relation where both the species interact with each other. For example, lion feeds on zebra, fox on a rabbit, grasshopper on leaves.

The predator and its specific prey population respond to each other dynamically. This means when the prey population for example rabbits, is over-exploited by a predator population or decreases due to a disease, the predator population goes down. Also, when the rabbit population increases drastically, the number of predators in the food chain increases due to the abundance of food. Some predators first kill the prey before feeding on them while others feed on the live prey.

With the development of species, some species flourished to exploit other species as food. The predator species in the course of time survived to develop certain strategies to hunt the prey. For example, the predators use camouflage, speed, and tolerance against poison producing prey. Similarly, the pre-species also evolved their strategies in order to avoid being recognized by a predator.

The survival number and reproduction of the prey population is regulated by the population of the predator. The relationship between the predator and the prey can be more complex because in certain circumstances one species might behave like a predator whereas with different species might act like prey.

When a predator feeds on a specific kind of prey, it might directly affect its own population in the long term. This is because the entire predator population is dependent on just one type of prey species which means in the coming future the number of prey will decrease. As a result, the food resource for the predator population will also decrease. This might result in direct competition among the members of the predator population, killing each other for food resources. Therefore, because of the scarcity of prey as well as direct competition both predators and the prey population restrict each other’s growth.

PHYSICAL SCIENCE !! please help <3

Answer:

C. A law describes the observation, while the theory explains the how or why.

Explanation:

So in general science, an observed phenomenon is the description of the scientific law. However the explanation of the phenomenon is called a scientific theory. Which would make this answer: c. A law describes the observation, while the theory explains the how or why.

Hope this helps!

Which of the following is a disadvantage of sexual reproduction?

Liula [17]

Answer: A) Slow to repopulate

------

Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.

Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.

_____is an interaction between species that affects both species negatively (-/-), as they utilize similar resources.

jolli1 [7]

An interaction between species that affects both species negatively (-/-) , as they utilize similar resources is called as Competition .

Competition :

Competition is a process in which the fitness of individual of one species is significantly lower than that of the individual of same or different species.

Types of competition :

For the necessities of life , it is divided into two types .they are as follows,

A) interspecific competition : it is a competition which occurs between the individuals of two different species having some requirements of life , e.g.,carnivorous animals such as tiger ,lion ,leopard etc .compete for the prey . in the forest habitat ,herbs and trees compete for sunlight , water space , minerals , and biological pollinators .

If the individuals of two different species have sme one or more requirement the the competition becomes very severe e.g., grassland is the common habitat for bison ,dear rabbits ,rats grasshoppers , etc .if thee is short supply of grass due to draught then the competition becomes severe

The survival of the consumers is determined by the quantity of grass required by each species ,ability to change the food and its capacity to migrate to new localities.

B) Intraspecific competition : it occurs between the individuals of the same species .this type of competition is very severe as all the individuals of the same species have almost common requirement of food ,habit etc .besides they also exhibits similar adaptations to fulfill their requirements ,e.g., animals of same species compete for water ,food and mates .

Intraspecific competition is the driving force behind evolution and natural selection .

Thus the Competition only negative impact on environment.
