How will halving the rabbit population affect the grass?
However, By doubling the rabbit popualtion the grass population begain to decrease, this is because rabbits feed of grass. The more rabbits to feed, the less grass there will be. However, halving the rabbit population caused the grass population to increase. This is because there where less rabbits to eat the grass.
How did doubling the rabbit population affect the grass snakes and hawks at first quizlet?
The grass population decreases because twice as many rabbits are feeding on it. The snake population would increase initially because of the increase in its food supply”the rabbits. The hawk population would also increase as the population of its food supply”the snakes”increases.
What will be the initial effect on the populations of hawks and rabbits?
If a disease strikes the snake population in the food chain shown, what will be the initial effect on the populations of hawks and rabbits? The population of hawks will increase. The population of rabbits will decrease.
What effect did removing predators have on prey gizmo?
Removing prey caused predator populations to decrease What effect did removing predators have on prey? Removing predators caused prey populations to increase Extend your thinking: In North America, many top predators, such as wolves, have been driven nearly to extinction.
How did increasing the snake affect the grass?
A. How did increasing the snakes affect the grass? Explain why: By increasing the population of the snakes, the size of the grass also increased because there were less rabbits, meaning that the snakes and hawks were eating more of the rabbits. With less rabbits less of the grass got eaten.
What was a major disturbance that caused the ecosystem to completely collapse?
Answer: A major disturbance that caused the ecosystem to collapse entirely, was when the snakes and the grass became diseased. A major disturbance that caused the ecosystem to stabilize at a new equilibrium.
What caused the ecosystem to stabilize at a new equilibrium?
A major disturbance that the ecosystem was able to recover completely from. oWhen there was a decrease in the rabbits, the ecosystem was able to recover and go back to normal. B. A major disturbance that caused the ecosystem to stabilize at a new equilibrium.
What does stabilize at a new equilibrium?
(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there’s no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.
Why does the population of each organism changed the way it did?
If populations don’t change very much over time, the ecosystem is in equilibrium . Populations decrease at higher levels of the food chain because they require more energy from other organisms.
Why does the population decrease at higher trophic levels?
Explain. The population size decreases because the higher on the food chain one looks, the fewer the number of organisms that occupy that level. This is because of the energy that is available from one level to the next has to decrease since it is used for life’s process.
How do predators and prey populations affect one another?
How do predatorand prey populations affect one another? When there are decreased predator populations, prey populations will increase. When there are decreased prey populations, predator populations will decrease, and whenthere are increased prey populations, predator populations will increase.
Why do you think the populations decrease as you go up the pyramid?
The pyramid of energy shows that the variety and number of species decreases as you move to higher trophic levels. This is also assuming that the organisms of the higher trophic level only eat the one organism. To maintain energy levels, higher organisms must eat more food than those at the lower levels.
Who has the greatest biomass in the food chain?
producers
What is the 10% rule what is its significance Why is energy lost?
Why is energy lost? 10% rule refers to the fact that only 10% of available energy is transferred from one trophic level to the next as an organism eats. It is significant because it determines the amount of organisms at each trophic level and creates the pyramidal shape.
What does the 10% rule mean?
The 10% Rule means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.
What is its significance Why is energy lost?
Answer Expert Verified The 10% rule means that approximately there will be only 10% energy transferred from a trophic level into another. That was because the consumer on the upper level will use the energy before it was consumed. About 90% of the energy used so only 10% remain will be transferred.
How energy is transferred?
There are three methods of energy transfer that we need to learn: conduction, convection, and radiation.
What are the three ways to transfer energy?
Heat can be transferred in three ways: by conduction, by convection, and by radiation.
What would happen if energy Cannot be transformed?
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.
Are humans just energy?
Quantum physics states that mass and energy are interchangeable, and consequently that mass is merely a manifestation of energy. This means that everything, including humans, is simply energy stored in mass particle form.
