100

It is the percentage of the quadrat area that is covered by one species (eg grass).

What is percentage cover?

100

They reproduce without gametes or the fusion of genetic material. 

What are asexual organisms?

100

By using colours, patterns, or materials animals use this to blend into the surrounding environment.

What is camouflage?

100

The variable that goes on the x-axis?

What is the independent variable?

200

This number represents the probability that two individuals selected from a sample will belong to different species.

What is SDI?

200

This type of relationship is when one organism hunts, captures, and consumes another organism. 

What is a predator / prey relationship?

200

This refers to the specific role or position that an organism occupies within an ecosystem. It encompasses all aspects of an organism's interactions with its environment, including its interactions with other organisms, its physical surroundings, and its resource utilization.

What is a Niche?

200

This classification system defines structural forms of vegetation in terms of the dominant plant form and the percentage of foliage cover of the tallest plant layer.

What is Specht's classification system?

300

It is how we would describe organisms living in and on a decaying log. 

What is a community?

300

These organisms prioritise high reproductive rates in environments where resources are abundant, but individual survival and parental care might be lower.

What are r-strategists?

300

This is a small, localised environment that can vary significantly from the surrounding area in terms of temperature, moisture levels, light exposure, and other environmental factors. An example would include the space under a rock. 

What are Microhabitats?

300

It refers to the natural pattern of distinct biological communities or habitats that are arranged in a specific order along an environmental gradient. For example, from high to low tide. 

What is zonation?

400

One is the size or extent of the area under study and the other refers to the time duration over which biological events or processes take place.

What are spatial and temporal scales?

400

Mutualism, Commensalism, Parasitism are types of this long-term relationship between two different species. 

What is symbiosis?

400

This is the one factor that distinguishes a community from an ecosystem. 

What is the abiotic environment?

400

One is a long strip of terrain in which all organisms are counted and/or measured. The other counts the number of individuals that lie on a straight line that cuts through a community.

What is the difference between A belt transect and A line transect?

500

Environmental factors that can limit the distribution and abundance of species in an ecosystem. Meaning each organism has their own range that restricts where that organism could potentially live.

What are tolerance limits?

500

A classification system based on climate. 

What is the Holdridge life zone system?

500

These ecosystems store carbon from the atmosphere in wood, have high biodiversity, and animal species rely on them for nesting hollows and variety of microclimates.

What are Old Growth Forests?

500

I calculate this by dividing the total number of different species (s) by the square root of the total number of individuals (N).
