Vocabulary
What is the meaning of an Abiotic factor?
A nonliving thing that impacts our ecosystems.
In a forest, a Tiger eats a Zebra in the forest with trees. Which things in that sentence were the organisms?
The Tiger and Zebra
2 monkeys live in a forest and one eats the other. (Actually happened), which one is the predator? Which is the prey?
The monkey that ate the other is the predator and the monkey that got eaten is the prey.
Explain the impact of water scarcity on planet populations in an ecosystem.
Water scarcity can impact planet population because without water plants can’t grow, and decreases the herbivore populations which could be prey and could led to a decrease of predators and animals overall.
What is the definition of population?
A group of interacting individuals of the same species located on the same area
What is the meaning of biotic factor?
A living thing that impacts an ecosystem
An owl eats things like rodents and birds. Is this a resource, competition, abiotic factor, or population?
The predator is Dave while the prey is the lobster, the friends are the consumers.
What human things do we do that hurt animals ecosystems, give examples.
Human activity affects a lot of things, like forest fires kill pray and animals making the animals have limited resource availability.
How can changes in climate, such as increased temperatures, affect resource availability and the populations of organisms in an ecosystem?
Changes in climate affect resource availability because it can kill plants because if the plant get to hot or cold which affects the population because if there is no food animals can die of starvation.
What does it mean to have competition?
When more than one individual or population in an ecosystem relies on the same limited resources.
Describe how competition for territory can influence the distribution and abundance of organisms in a habitat.
If territory is so low that organisms have to compete, then animals might die of a heat stroke or get too cold and die, making either way decrease the population.
an eagle eats an owl, Who's the predator and who's the prey?
eagle is the predator and owl is prey
Explain how a sudden increase in food resources might impact the population of herbivores and their predators in an ecosystem.
A food increase in an ecosystem may increase the number of animals which can impact the population by increasing the number of animals which when the food sources dies down can turn into overpopulation.
Describe the differences between abiotic and biotic factors in an ecosystem.
The differences between abiotic and biotic factor is that abiotic factors don't move and provide things like shelter while biotic factors depend on population, can ruin the land, they move. (This is only an example this question has multiple answers).
What does it mean to have limited resources?
Something that is needed by organisms is not infinite and doesn't have a lot more of it.
Explain how the introduction of a new resource can alter the population dynamics within the ecosystem.
Ex:The introduction of a new resource could be positive and negative. For example, an animal could be allergic or it will exist again because all the animals will love it and take it all.
2 crocodiles go hunting, crocodile 1 hunts, 2 birds, 3 pigeons, and 5 fishes, Who are the predators and who is the prey?
The 2 crocodiles are the predators and the 2 birds, 3 pigeons, and 5 fishes are the prey.
An animal goes extinct, what impact does it make.
That animal could have been prey which means that predators have to adapt or find new food or the predators could go extinct as well.
What are the effects of overfishing on marine ecosystems?
Overfishing can be a problem because if there is no more fish, which is prey, the predator population will go down and we will not have fish as a food source anymore.
What is a primary consumer?
An organism that gets its energy by feeding on producers in the food chain.
How does an increase in a specific resource, such as light, affect the populations of primary producers in an ecosystem?
If, for example, light increases, it affects in a positive way because all the plants grow, also, another example is water, so every animal could drink as much as they want.
One day a snake wanted a mouse so he ate one. Then the girl ate the snake. Then an eagle ate the girl. Then a leopard ate the eagle. Then a tiger ate the leopard. Then a brown bear ate the tiger. How many examples of preadaptation was that?
6 examples
One day a guy named bob when fishing but 5 hours and he caught no fish. Then Bob said "Wow this area must have---"
A.overpopulation
B.Limited resources
C.Ecosystems
D. preys
B
What is the difference between population and ecosystem?
Ecosystem includes all the factors including abiotic factors and biotic but the population is just the biotic factors in an area.
