chapter 18 science
Terms in this set (32)
describes the nonliving part of the environment, including water, rocks, light, and temperature
the part of Earth where life exists; includes all of the living organisms on Earth
describes living factors in the environment
an organism that eats animals
the largest population that an environment can support at any given time
the evolution of two species that is due to mutual influence, often in a way that makes the relationship more beneficial to both species
a relationship between two organisms in which one organism benefits and the other is unaffected
all populations of species that live in the same habitat and interact with each other
the study of the interactions of living organisms with one another and with their environment
a community of organisms and their abiotic environment
a triangular diagram that shows an ecosystem's loss of energy, which results as energy passes through the ecosystem's food chain; each row in the pyramid represents a trophic (feeding) level in an ecosystem, and the area of a row represents the energy stored in that trophic level
the pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms
a diagram that shows the feeding relationships between organisms in an ecosystem
an organism that eats only plants
a relationship between two species in which both species benefit
an organism that eats both plants and animals
a relationship between two species in which one species, the parasite, benefits from the other species, the host, which is harmed
a group of organisms of the same species that live in a specific geographical area and interbreed
an organism that eats all or part of another organism
an organism that is killed and eaten by another organism
a relationship in which two different organisms live in close association with each other
Distinguish between biotic and abiotic parts of the environment and give examples of each
Biotic means living organisms and abiotic is non living organisms
Explain how populations and communities are related
Populations and communities are related because a lot of populations make up a community.
Describe how the abiotic parts of the environment affects ecosystems
Abiotic parts of the environment affects ecosystems because some animals use camouflage to hide into things and the weather can also affect the ecosystem.
Order the 5 levels of environmental organization and give an example of each
Biosphere- The areas where all life is able to live on Earth.
ecosystems- abiotic and biotic things in an environment.
community- a group of populations that live together
population- a group of organisms that live together
organism- is a animal that is by itself
Distinguish between a food chain and a food web
The pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms while a food web is A diagram that shows the feeding relationships between organisms in an ecosystem so with that being said a food web is the bigger picture.
Explain how energy flows through a food web
A food web is many organisms connected to each other going from one another to the next but it is all in a ecosystem.
Describe how the removal of one species affects the entire food web
When one species is gone, one source of food is gone affecting how much the other organisms eat and the organisms that eat them will eat thinner prey because they lost a source of food and so on.
Describe the 2 types of competition
competition happens between individuals within a population. Competition also happens between the populations
Distinguish between mutualism, commensalism, and parasitism
Mutualism - helping of TWO species of animals, Commensalism - helping of ONE species of animals and not affecting the other, parasitism - the helping of ONE animal,the host, and the harming of another.
Give an example of coevolution.
Parasites and a host.
Discuss 3 adaptations prey/predators have developed to make their lives easier
Camouflage, it helps prey escape from predators or it helps predators get prey
defensive chemicals the organism can spray them if a threat gets to close fo comfort
warning coloration helps the predator not eat the animal because it may or may not be poisonous.
