Does algae increase pH or decrease pH of water?
Algae draws all available CO2 out of water, causing its pH to increase.
What caused the Illinois River largemouth bass population low?
Pollution was a small factor but the largest factor is the spread of the Asian Carp which feed on algae and surface insects. This causes a disruption in the entire river ecosystem all the way to the largemouth bass causing a decrease in available food and therefore a decrease in population.
If the owl population increases what will happen to the number of voles and why?
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.
What is the factor most likely to result in a decrease in the size of a specific population is?
An increase in predation pressure or a decrease in food availability are factors most likely to result in a decrease in the size of a specific population. These factors can lead to increased mortality rates and reduced reproductive success, ultimately causing the population to decline in numbers.
Will clear pool covers decrease algae growth?
No if any thing it will increase it as algae uses sunlight
What happens to the population of a certain species when the predators decrease?
When predators die, that means more of the prey live to maturity. That means that more babies are born, resulting in a larger population size. However, as time goes on, this growth in population can get out of hand, causing the prey to have a food shortage, causing animals to die. All the weak animals means more food for the predators, which also means they have more babies. They have a food shortage too, causing the population to decrease... and the cycle begins again.
What is the relationship between the size of the predator population and the size of the prey population?
Let's put it this way. Say you have a killerwhale and a penguin. Killerwhales are major predators to penguins. Now, say the killerwhale population increases. The penguins would be eaten more by the killerwhales, then causing a population decrease for the penguins. If the population decreases, they're won't be enough penguins, and they most likely will become extinct, as well as causing a population decrease for the killerwhales as well. Whereas, vis versa, they're were a killerwhale population decrease. The penguins would be less hunted, therefore, creating a population increase for the penguins.
What effect would there be on the marine environment if there was a large decrease in the number of blue green algae in an area?
There would be a decrease in productivity because the algae "fix" nitrogen needed for protein production.
After a rabbit population reaches the carrying capacity of its habitat the population of rabbits will most likely?
stabilize or decline due to limited resources like food, water, and shelter. This can lead to increased competition, disease spread, or predation, causing the population to resist further growth.
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 do parasites serve as density-dependent limiting factors?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
