Food Chains & Energy
The two things that move from one organism to another in a food chain.
What are energy and matter?
The type of consumer that a grey wolf is.
What is a carnivore?
The meaning of the word biotic.
What are living or once-living parts of an ecosystem?
This is an instinct: monkeys riding bikes, groundhogs hibernating, dogs shaking hands, or cats sitting on command.
What is groundhogs hibernating?
The reason decomposers are important to an ecosystem.
What is breaking down dead organisms and adding minerals and nutrients to the soil?
In the food chain crane → boar → grey wolf, energy and matter move to the wolf through these organisms.
What are the crane and the wild boar?
The role of a grey wolf when it hunts and eats a wild boar.
What is a predator?
The difference between a habitat and a niche.
What is a habitat being where an organism lives and a niche being its role in the ecosystem?
One reason animals migrate.
What is to avoid weather that is too hot or too cold?
The type of symbiosis in which both organisms benefit.
What is mutualism?
The main source of energy for most food chains.
What is the Sun?
The type of consumer that eats both plants and animals.
What is an omnivore?
The reason biotic and abiotic factors are both important to an ecosystem.
What is that they work together and affect how organisms survive?
One reason some animals hibernate.
What is to reduce breathing and heart rates to conserve energy?
The type of symbiosis in which one organism benefits while the other is neither helped nor harmed.
What is commensalism?
The difference between how producers and consumers get energy.
What is producers getting energy directly from the Sun while consumers get energy by eating other organisms?
The interaction that occurs when a hare and a lynx drink from the same river.
What is competition?
The difference between a community and a population.
What is a community including populations of different kinds of organisms, while a population includes organisms of the same kind?
What are the examples of adaptations that help organisms survive: rattlesnakes lying coiled under a bush, salmon and red knots migrating to reproduce, and bears eating a variety of foods?
What are all of the above?
The type of symbiosis in which one organism benefits while the other is harmed.
What is parasitism?
The amount of available energy that a deer passes to a wolf.
What is only a small amount of energy?
The role of a lynx that uses its speed and claws to hunt and helps control the mouse population.
What is its niche?
The difference between a food chain and a food web.
What is a food chain showing one pathway of energy flow while a food web shows multiple connected pathways?
Which is a learned behavior: birds building nests, spiders spinning webs, dogs sitting on command, or salmon migrating to spawn?
What is dogs sitting on command?
The way decomposers help recycle matter in an ecosystem.
What is breaking down dead organisms and returning nutrients to the environment?
