What would be the decrease in population a year if no children were born?
Without births, the population decrease would be the same as the number of deaths, which is generally between 57-58 million a year.
If a population of caterpillars feeds on the leaves of trees in a forest and is in turn food for birds that eat them off of the trees what adaptation would be most likely to evolve?
An adaptation that could evolve is for the caterpillars to develop toxic chemicals in their bodies that make them unpalatable or harmful to the birds. This would help the caterpillars defend themselves from predators and increase their chances of survival.
What would be the effect of removing an organism from the food web?
Removing an organism from a food web can disrupt the balance of the ecosystem. It can lead to an increase in the population of its prey and a decrease in the population of its predators, impacting the overall biodiversity and stability of the ecosystem.
Does the population size increase or decrease at higher trophic levels in the pyramid of numbers of an ecosystem consisting of any herbivores and birds feeding on the insects?
Population sizes decrease at higher trophic levels. If they increased the insects population would decrease meaning there would be less food available for the birds so their population size would then decrease. Look at the relationships between predator and prey species for more information
Which change would decrease the population of small fish the most?
Overfishing of small fish would decrease their population the most since it directly reduces the number of individuals in the population.
Why would there be a decrease in the number of orange striped caterpillars if there was an increase of gypsy moth caterpillars on the same leaf?
A decrease in the number of orange striped caterpillars in the presence of an increase in gypsy moth caterpillars could occur due to competition for limited resources, such as food and habitat. Gypsy moth caterpillars are known to be voracious feeders, which may lead to overconsumption of the leaves and reduction in available food for the orange striped caterpillars. Additionally, the presence of a higher population of gypsy moths could increase predation or parasitism, further impacting the survival rates of the orange striped caterpillars.
Why would removing snakes from a food web might result in a decrease in the grasshopper population?
there would be no snakes to eat the frogs and with more frogs their would be less grasshoppers
What will happen if the plankton population decrease?
The population of zoo plankton would decrease.
How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
How can a dam affect the population of salmon?
it would decrease population
A population of an animal would decrease because of what?

What population would decrease if all the grasshoppers died?
The grasshopper population.
What population would decrease if all grasshoppers died?
The grasshopper population.
What would be the decrease in population a year if no children were born?

What is population implosion?
It would be the opposite of a population explosion. The population would decrease drastically and rapidly instead of increasing.
What would happen if the population increased on work?
there would be a decrease in unemployment
