What is Env Sci
This branch of science studies how living things interact with each other and different populations.
What is ECOLOGY?
This branch of science includes research from ecology, biology, zoology, oceanography, atmospheric science, soil science, geology, chemistry
What is Environmental Science?
When the death rate is greater than the birth rate this happens to the population.
What is DECREASES?
This includes many different HABITATS
What is an ECOSYSTEM
An interaction in which one organism kills and eats another is called:
What is PREDATION?
The place where organisms live and get all they need to survive.
What is HABITAT?
This group of organisms is physically similar and can reproduce.
What is a SPECIES?
This estimate of a population is an approximation of number based on reasonable assumptions.
What is SAMPLING?
This includes all the members of a species in an area.
What is a POPULATION?
Food, space, and weathewr are all examples of these things that prevent populations from increasing.
What is a LIMITING FACTOR?
These are factors that help an organism avoid being captured or killed by predators.
What are PREY ADAPTATIONS?
An organism's particular role or how it makes its living:
What is a NICHE?
This technique of studying populations involves the capture and release of animals being counted.
What is MARK and RECAPTURE?
The living parts of an ecosystem.
What are BIOTIC factors?
There are 3 types (MUTUALISM, COMMENSALISM, and PARASITISM) of this relationship where species either benefit or harm another species.
What is SYMBIOSIS?
Plants, trees, animals, and people are all examples of this.
What are BIOTIC factors?
This relationship involves one organism living on or in another and harming it by doing so:
What is PARASITISM?
The number of individuals divided by the size of the area.
Water, Sunlight, Oxygen, Temperature, and Soil are all forms of this part of an ecosystem.
What are ABIOTIC factors?
These are environmental factors that prevent a population from increasing.
What is a LIMITING factor?
Scientists study this phenomenon where organisms change over time to better suit their living environment.
What is NATURAL SELECTION?
A relationship where BOTH species benefit is called:
What is MUTUALISM?
Name the order of the 4 Ecological organizations from smallest to largest
What is ORGANISM, POPULATION, COMMUNITY, and ECOSYSTEM?
Organisms need this combination of sunlight and CO2 to make food.
What is PHOTOSYNTHESIS?
Carrying capacity can be described as:
What is the largest population an environment can support?
