invasive Species
non-native organism that causes harm to an ecosystem.
what is an invasive species
the level of an organism it occupies in a food web
What is a trophic level
The interaction between two different organisms living in close physical association, typically to the advantage of both.
What is Symbiosis
The concentration of toxins in organisms as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
What is biomagnification?
a natural process where nitrogen moves between the atmosphere, soil, plants, animals, and back again.
What is the nitrogen cycle?
how can invasive species be introduced to new environments
what is accidental release, and intentional releases,
In a food chain, which trophic level has the most biomass
what is primary producers
a myth bird eating food remnants out of a crocodile's teeth, what kind of relationship is this?
What is Mutualism?
How does DDT biomagnify in a food chain involving plankton, small fish, large fish, and birds of prey
The DDT chemical gets stored in the fatty tissues of organisms.
the process of something becoming similar to something else.
what is Assimilation?
some economic costs associated with invasive species
what is decreased property values
The name of the organism that decomposes dead organic matter
what is Decomposers
A tick living on a cat's skin and drinking away its blood, what kind of relationship is this?
What is parasitism?
how can mercury biomagnify in a marine ecosystem?
it can accumulate in the tissues of organisms as it moves up the food chain
the process of converting natural nitrogen compounds into ammonia
What is Ammonification
what can be an ethical consideration of using bio control methods for invasive species management
organisms that eat or infect targeted species
What kind of animals are usually primary consumers?
rabbits, mice, or deer
a remora fish attaching itself to a shark and is eating left over remains of food, what kind of relationship is this?
What is commensalism?
how can factors influence the rate and extent of biomagnification in a particular ecosystem.
through the structure of the food web, or environmental conditions
when organisms die, decomposers like bacteria and fungi break down organic matter, releasing nitrogen in the form of ammonia back into the soil.
what is Ammonification
how can someone identify invasive species in a local area
field guides to identify plants and animals in your area, often with pictures.
Why is there usually less carnivores than herbivores in an ecosystem
what is energy transfer between trophic levels is not 100% efficient, with about 10% of energy transferred to the next level.
How can symbiotic relationships among organisms in an ecosystem influence populations
creates different types of interactions in the ecosystem.
True or False: Biomagnification only involves DDT
False, Biomagnification does not only involve just DDT
a certain bacteria that converts ammonia into nitrite and then into nitrate that which plants can absorb through their roots.
What is Nitrification
