What limits the size of a squid?
Prey size and availability.
The size of the population can affect the size of a predator population?
A prey
What is the population size of predator species directly controlled by?
The population size of predator species is typically controlled by the availability of prey, competition with other predators, and environmental factors like habitat and climate. The population size can fluctuate based on these factors, leading to dynamic predator-prey relationships.
What factor limits the growth of the prey population?
The growth of the prey population is limited by factors such as predation, availability of food and resources, competition with other species for resources, diseases, and environmental factors like habitat destruction or climate change. These factors can reduce the prey population size or prevent it from expanding beyond a certain level.
Look at the prey's population size at the end of the graph. How will this population size most likely change next?
The prey population size at the end of the graph appears to be decreasing, indicating a likely continued decline in the population size in the near future. This could be due to factors such as predation, resource depletion, or environmental changes impacting the prey species.
What is meant by 'predator prey cycle'?
the predator-prey cycle is the increase and decrease in population size of the predator and its prey
A resource so scarce that it limits the size of a population is called a?
a limiting factor
The population size of a predator species is directly controlled by?
The population size (number) of a predator species is directly controlled by the availability of a food source (prey). The more prey available, the greater growth in the number of predator species.
Write the formula for population growth without limits?
In a population without limits, there will be an increase in the population size. For that we will use the equation (dN/dt) = 1.0 N where N is the number of individuals in the population and (dN/dt) is the rate of change in the number of the population over time.
When a population size fluctuates within limits in response to the environment but overall maintains a stable size it is said to be in what?
dynamic equilibrium
What limits the number of species that can survive in a habitat?
Various limiting factors can retard the growth of a predator population. The greatest limiting factor is generally the availability of prey. The predators depend on the prey population for sustenance, and if prey population dwindles, predator population does as well. Other factors can limit a population as well, such as the abudance of abiotic resources (water, etc) and territory.
When a population size fluctuates within limits in response to the environment but overall maintains a stable size it is said to be in?
C. dynamic equilibrium
