Ch. 1 Ecology Exam

Organisms that create food for themselves from the Sun.

Producer/Autotroph

A living thing

Organism

The same type of animal as another

Species

How much organisms in an area (that are of the same species)

Population

Combined populations in an area

Community

Combined biotic and abiotic populations in a small area

Ecosystem

Combined biotic and abiotic populations in the same type of place, such as a rainforest

Biome

The entire world

Biosphere

An organism that eats plants, meat, or both

Consumer/Heterotroph

Living thing

Biotic Factors

Non-living thing

Abiotic Factors

A cycle where carbon is reused

Carbon Cycle

A diagram that explains what an organism eats in a community

Food Web

A diagram that explains the energy flow of an area

Energy Pyramid

An organism that only eats plants

Herbivore

An organism that only eats meat

Carnivore

An organism that etas both plants and meat

Omnivores

A process where an autotroph produces energy for itself.

Photosynthesis

A process where cells get energy from glucose

Cellular Respiration

Competition between different species

Interspecific Competiton

Competition within the same species

Intraspecific Competition

A relationship that benefits both organisms

Mutualism

A relationship that benefits one and harms the other

Parasitism

The measurement of a population per unit of land area

Population Density

When a population size increases dramatically over a period of time. A J-curve.

Exponential Growth

Occurs when a population’s growth slows, and then stops, following a period of exponential growth. A S-curve.

Logisitic Growth

All of the biotic and abiotic factors in the area where an organism lives

Habitat

A smaller part of the habitat that possesses specific physical conditions that are beneficial for an organism.

Microhabitat

The variety of environmental conditions that an organism can survive and reproduce

Tolerance

The assortment, or variety of living things in an ecosystem.

Biodiversity

The total number of individuals in a given area at a specific time

Population Size

How much organisms an area can sustain with its resources

Carrying Capacity

Spiders, deers, sharks

3 examples of Consumers
