It is a measure used in ecology to quantify the diversity or richness of species in a specific area or community. This index takes into account both the number of different species present and the relative abundance of each species

What is Simpson's Diversity Index?

100

The grouping of organisms in terms of similarities in morphology, anatomy and biochemistry.

What is classification?

100

The living organisms of a large area defined by its climate and dominant plant species.

What is a biome?

100

A tool used to identify organisms in a habitat or ecosystem.

What is a dichotomous key?

100

When you provide an answer from a number of possibilities; recognise and state a distinguishing factor or feature.

What is identify?

200

This is the number of species within a defined region. 

What is species richness?

200

This system is based on the structural characteristics that are similar between organisms.

What is Linnaean classification?

200

A biological community of interacting organisms and their physical environment.

What is an ecosystem?

200

The variable that goes on the y-axis. 

What is the dependent variable?

200

When you give an account of an event, pattern or process, or of the characteristics or features of something.

What is describe?

300

These examples restrict species living in an aquatic environment:

1) Oxygen does not dissolve easily in water, 

2) Access to light is limited 

3) High salinity in the water  

What are Limiting Factors?

300

One is the non-living factors that affect an organism’s ability to survive. The other is the living components of an environment.

What is the difference between abiotic and biotic?

300

Uses height of tallest plants and the foliage cover of the tallest plants to classify an ecosystem.

What is Specht's classification?

300

Examples include dissolved oxygen, light, temperature, depth, distance from low tide, pH and wind speed. 

What are abiotic factors?

300

When you establish, conclude or ascertain after consideration, observation, investigation or calculation; decide or come to a resolution. 

What is determine?

400

This refers to the proportional representation of different species within a particular ecosystem or community.

What is relative species abundance?

400

The taxon level where two different species have the most features in common.

What is genus?

400

A small habitat that may be different from the surrounding larger habitat

What is a microhabitat?

400

This is a method of selecting a sample so that each measurement in the study has an equal chance of being selected.

What is Random sampling?

400

When you arrange, distribute or order in classes or categories according to shared qualities or characteristics.

What is classify?

500

One is a specific location with a particular set of abiotic factors, where an organism usually lives. The other is the conditions in which the organism lives.

What is the difference between habitat and environment?

500

By doing this fragile areas can be protected and land clearing prevented. It also enables an understanding of species diversity and the maintenance of natural resources in a sustainable manner.

What is naming ecosystems?

500

It refers to the vertical layering of different ecological communities or habitats within a specific environment. These layers are typically defined by factors such as light availability, temperature, water availability, and other physical and biological conditions. For example, from Canopy to Forest floor in a Rainforest.

What is stratification?

500

The technique used to collect insects, especially in long grasses.

What is sweep netting?

500

When you display recognition of similarities and differences and recognise the significance of these similarities and differences.

What is compare?
