Question 1: Herbivores

Answer:

Consumers that eat only plants An example of an herbivore in the Amazon rainforest is a blue macaw.Herbivores are an important part of the food chain and carbon cycle(as a heterotroph)

Question 2: Carnivore

Answer:

A consumer that eats only animals.An example of a carnivore in the Amazon rainforest is a jaguar.Has a very late role in the food chain, usually last to obtain energy.

Question 3: Autotroph

Answer:

organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer In example of an autotroph in the amazon rainforest is the açaí palm Is important because all life relies on autotrophs also called primary producers

Question 4: Food Chain

Answer:

A series of steps in which organisms transfer energy by eating and being eaten The amazon rainforest has specific food chains showing the transfer of energy.Is important in understanding more about the transfer of energy and how the relationships of organism work with the 10% rule energy transfer

Question 5: Biotic Factor

Answer:

Any living part of the environment with which an organism might interact An example of this in the amazon rainforest could be the lush foliage in which many herbivores consume or could be used for shelter by prey.Is important because biotic factors affect the type of life that is able to live in a specific ecosystem.

Question 6: Photosynthesis

Answer:

A process used by plants and other autotrophs to capture light and energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates, such as sugars and starches.An autotroph that would use this process in the amazon rainforest would be an açaí palm.Is an important part of the carbon cycle making the glucose which is then ingested by a heterotroph.Also is the start of the flow of energy through ecosystems along with chemosynthesis.

Question 7: 10% rule of energy transfer

Answer:

when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on When a herbivores eats a producers, the herbivores will only get 10% of the producers energy.Is important to understand more about the movement of energy and the relationship between different trophic levels.

Question 8: Abiotic Factor

Answer:

physical, or nonliving, factor that shapes an ecosystem In the amazon rainforest a abiotic factor would be the high amount of precipition.Is important because abiotic factors affect the type of life that is able to live in a specific ecosystem.

Question 9: Producers

Answer:

Organisms that produce their own food; autotrophs An example of a producer in the amazon rainforest would be an açaí palm.Is important because is the starting part of the food chain and web.

Question 10: Habitat

Answer:

An area in which an organism lives, including the biotic and abiotic factors affect it.An example of a habitat in the amazon rainforest would be a palm forest.Is important in understanding how biotic and abiotic factors affect certain habitats and what organism live in those habitats

Question 11: Food Web

Answer:

network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem The amazon rainforest is an example of an ecosystem that would have a specific food web.Is important in understanding the relationship organisms have in a specific ecosystem in a more complex diagram than the food chain.

Question 12: Decomposer

Answer:

An organism that break down organic matter.An example of a decomposer is a mushroom Has in important role in decomposing plants and animals into detritus which is then eaten by detrivores.

Question 13: Detrivore

Answer:

Organism that feed on plant and animal remains An example of a detrivore is a worm Has in important role in the movement of energy throughout food webs by "cleaning up" and getting energy from that.

Question 14: Chemosynthesis

Answer:

process in which chemical energy is used to produce carbohydrates An example of an autotroph that uses chemosynthesis would be sulfur bacteria Is an important use for autotrophs that don't have a direct access.

Question 15: Trophic level

Answer:

Each step in a food chain or food web An example of a trophic level is the primary producer level.(1st level) Is important because break up the food chain and webs into more comprehensible levels. Each level takes 10% of the energy from the last level.

Question 16: Energy Pyramid

Answer:

A diagram that shows the amount of energy that moves from one feeding level to another in a food web Their is an energy pyramid for every ecosystem like the Amazon Rainforest Important to understand the 10% rule in a diagram

Question 17: Heterotroph

Answer:

organism that feed by consuming other living things; also called a consumer An example of a heterotroph in the amazon rainforest would be a sloth.Is important because heterotroph need autotrophs and other heterotrophs in order to survive.

Question 18: Organism

Answer:

Any living thing An example of an organism in the amazon rainforest is a toucan.Is important because cause changes in ecosystems constantly, have a big role in the carbon cycle, and take in and transfer energy throughout food chains and webs.

Question 19: Omnivore

Answer:

A consumer that eats both plants and animals An example of an omnivore in the amazon rainforest would be a tree frog.Is important in maintaining stable(not too high) populations in an ecosystem because of the variety of organisms that they eat.
