What is the difference between autotrophs and heterotrophs?
Autotrophs are mainly producers, they produce their own form of energy that they live off of. While heterotrophs feed off of other organisms and have to find and consume forms of energy.
What are herbivores, carnivores, omnivores, and detrivores?
Herbivores are animals that eat only plants, carnivores are animals that eat only meat, omnivores are animals that eat both meat and plants, and detrivores are animals that eat things that are dead.
What is a keystone species? Give an example.
A keystone species is a species that an organism cannot live without for example a starfish in a certain community is a keystone species.
What is a trophic Cascade diagram?
It is a diagram that shows what organisms in an ecosystem eat and how they effect the other organisms directly and indirectly.
What is a food web?
It is a diagram that shows what organisms in an ecosystem consume starting with a producer and ending with a tertiary consumer.
What’s the difference between a food web and a trophic cascade diagram?
Food webs only show the things the organisms consume while the cascade diagrams show that and the effect it has on other organisms both directly and indirectly.
Name the other of trophic levels in a food web from bottom to top.
Producer, primary consumer, secondary consumer, and tertiary consumer.
If a trophic Cascade diagram shows a bass having negative impact on minnows and minnows having negative effect on zoo plankton and that negatively effecting phytoplankton which positively effects carbon influx what is the indirect effect from the bass to the carbon influx if the bass die out? Why?
Bass dying will have a negative effect on the carbon influx because due to it eating the minnows less the zoo plankton will be eaten more and feed less on the phytoplankton their for their will be more phytoplankton so the carbon influx will decrease.
