Energy Pyramids
The bottom level of an energy pyramid contains what types of organisms?
What are "producers?"
Organisms that make their own food are called...
What are "producers?"
In this symbiotic relationship, one organism benefits while the other is harmed.
What is parasitism? (PARASITE and HOST)
Food chains always begin with a __________.
What is a "producer?"
What are the two types of "succession?"
What are "primary" and "secondary?"
What is the difference between "primary" consumers and "secondary" consumers?
Primary consumers eat just the producers, and secondary consumers eat other animals.
What is the difference between a "population" and a "community?"
A population is all of the same species, and a community includes many different species.
In this symbiotic relationship, resources like water, food or mates are limited, therefore fighting could occur between species.
What is "competition?"
Food chains and webs show pictures of the living things, joined by _________ showing the path of energy.
What are "arrows?"
This type of "succession" occurs when an ecosystem experiences a major change where only rocks are present; no soil at all.
What is "primary succession?"
What is "it decreases?"
This refers to the amount of available resources that may only allow a certain number of organisms to successfully live in an area.
What are "limiting factors?"
This symbiotic relationship occurs when one organism seeks out or hunts another, then kills and eats it.
What is "predation?"
Organisms like fungi and bacteria are shown in food webs consuming (getting energy from) a wide variety of other organisms of all shapes and sizes.
What are "decomposers?"
After floods, tornados or even fires, although there is damage, soil typically remains. What type of "succession" would occur here?
What is "secondary" succession?
If there were 20,000 energy units available at the "producer" level(bottom), how much energy would then be available to "primary" consumers?
What is 2000?
This is the process where nature heals a damaged ecosystem, and new life slowly begins to inhabit the area.
What is "succession?"
Living things interact with other living things, plus they interact with non-living things also. What do we call these "living" and "non-living" parts of the ecosystem?
What are "biotic" and "abiotic" factors?
This diagram shows multiple paths of energy traveling throughout an ecosystem.
What is a "food web?"
The top level of an energy pyramid includes ____________ consumers(top predators).
What are "tertiary" consumers?
When the process of succession is happening, these are the first species to populate the area.
What is "commensalism?"
What is the difference between a food web and a food chain?
What is "food chains show only a single path of energy, and food webs show several overlapping food chains in an ecosystem?"
Events like volcanic eruptions cause significant changes to ecosystems. What type of "succession" occurs after such an event?
What is "primary" succession?
