Energy Flow
This is the ultimate source of energy for almost all organisms on Earth.
What is the sun?
This is the term used for organisms that feed only on plants.
What are herbivores?
A group of the same species of organism which lives in the same area and uses the same resources is called this.
What is a population?
What is matter?
What is a producer/autotroph?
The arrows in a food web/chain show this.
What is the direction that energy flows in an ecosystem?
Humans, bears, and raccoons are examples of this type of consumer.
What is an omnivore?
Two species of birds competing to eat the same insect, which is sitting on a blade of grass describes this level of organization.
What is a community?
These three processes are the main processes of the water cycle.
What are evaporation, condensation, and precipitation?
This is a way that humans negatively impact natural ecosystems.
Answers may vary
The % of energy that can be transferred from one trophic level to the next.
What is 10%?
This niche of organisms can feed on any dead organisms in an environment.
What are decomposers?
Ecosystems include the interaction of both ________ and _________ factors.
What are abiotic and biotic?
These two forms of carbon are found in the atmosphere.
What are carbon dioxide and methane?
The energy pyramid is a digram shaped like a pyramid so largest at the bottom and tapers to a point at the top. The diagram is pyramid shaped for two reasons.
The amount of energy decreases as it flows up.
The number of individuals decreases at each level as it goes up.
What are two reasons that a predator can only get a small amount of available energy from prey that it eats?
Potential answers:
Some parts of the prey are not digestible.
The predator uses energy to catch the prey.
The prey uses energy to try to stay alive.
This type of organism is at the bottom of food chains.
What are autotrophs?
This is the largest level of ecological organization and encompasses all the places that organisms exist on Earth.
What is the biosphere?
This type of organism releases carbon dioxide through respiration.
What are heterotrophs?
This is the main difference between the flow of energy and matter in the ecosystem.
These are the six types of heterotrophs.
Describe some specific ways that biomes/ecosystems are connected with other biomes/ecosystems.
River systems connect biomes. Water, carbon, and nitrogen cycle move materials to different areas of the world. The ocean regulates global temperatures.
These are the five steps to the nitrogen cycle.
What are fixation, nitrification, assimilation, ammonification, and denitrification?
