Biology Quiz Sep 23

Lesson 1-3 + Silence of the Frogs

What does Abiotic mean? Physical rather than biological; not derived from living organisms.
What does Biotic mean? Relating to or resulting from living things, especially in their ecological relations.
What is the definition of Community? An interacting group of various species in a common location.
What's an example of a Community? A forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi
What is the difference between a food chain and a food web? Food webs show how plants and animals are connected in many ways to help them all survive. Food chains follow just one path of energy as animals find food
Where does the energy go when you move up the trophic levels? The amount of energy decreases because there is less to eat for the organisms at the top trophic level, this means that there are fewer organisms to eat for the top animals, and more to eat for the bottom organisms.
Which trophic level includes the most biomass? The trophic level that contains the greatest biomass in most ecosystems is the producers.
What trophic levels contain carnivores? Anything above the first and second trophic levels include carnivores.
What would happen if an animal at the top trophic level were to go extinct? The animals in the below levels would thrive and overpopulate.
Is a tree considered an ecosystem? Yes, this is because there are multiple biotic organisms and abiotic things that are on trees.
Do humans influence abiotic factors in the environment? Yes, humans influence many things including, biotic and abiotic factors.
What is the difference between a frogs food chain and a tadpoles food chain? Because tadpoles live in completely different ecosystems then frogs there food chains are really different. One change being, tadpoles are herbivores and eat algae, while frogs are carnivores.
What are some reasons for the disappearance of frogs? There are some issues like deforestation and expanding towns, but there are also bigger issues like pollution, acid rain, and UV radiation.
Why are frogs affected by UV radiation? The skin on frogs is really thin, this is because frogs breathe through there skin. But because their skin is really thin, they are really susceptible to Ultra Violet radiation.
Why are frogs a good bioindicator? Frogs are disappearing because of humans, if we see that frog populations have stopped going down and starting to flatten out and even go up, we know we are doing good.
Why are scientist concerned? Frogs show the health of their ecosystems. If tadpoles are dying then the health of the pond or swamp they're in is really bad, but if it's the frogs dying, we know that the surrounding area is not doing to well.
What is a food web? A system of interlocking and interdependent food chains.
