The term for trees that lose leaves in the winter.


Deciduous

100

Term for a species that has a disproportionately large effect on its natural environment relative to its abundance; it holds an ecosystem together

 Keystone

100

Three types of biodiversity are ecosystem, genetic, and _________

Species

100

This is the source of energy in the ecosystem?

Solar radiation

100

a collection of ecosystems sharing similar climatic conditions.

Biome

200

Temprature and pH are examples of this type of factor.

abiotic

200

The maximum number of species that can be sustainably supported by a given environment.

Carrying capacity

200

This calculated index uses the number of individuals and the number of species types to give a value of biodiversity

Simpson's reciprocal index

200

This trophic level has the most energy in a food web.

producers

200

Term for The gradual change in species populations along a gradient of abiotic factors

zonation

300

This is a symbiotic relationship in which both species benefit.

Mutualism

300

A relationship between two species where one is benefited and the other is harmed. 

Parasitism

300

One of the biggest threats to biodiversity are these types of species, which have been brought to an area that they are not endemic to

Invasive

300

This trophic level consists of carnivores that eat herbivores.

secondary consumers

300

This are the main factors that governs the distribution of biomes

Temperature and precipitation

400

This type of population growth is characterized by an S-shaped graph that reaches a carrying capacity. 

Logistic growth

400

 a species chosen to raise support for biodiversity conservation in a given place or social context

Flagship

primary

500

Fires and other natural disasters are this type of limiting factor.

Density independent

a technique used to estimate the distribution and abundance of organisms in an area by randomly placing squares in the area being studied.

quadrat sampling

500

What is the organization that produces the red list of threatened and endangered species. 

IUCN
