Biodiversity
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?
The taxon level where two different species have the most features in common.
What is genus?
The grouping of organisms in terms of similarities in morphology, anatomy or biochemistry.
What is classification?
A technique that uses different layers called strata within a habitat to analyse patterns in ecosystems. It enables the collection of representative data from the area.
What is stratified sampling?
When you provide an answer from a number of possibilities; recognise and state a distinguishing factor or feature.
What is identify?
This is the number of species within a defined region.
What is species richness?
This system is based on the structural characteristics that are similar between organisms.
Linnaean Classification
The number of individuals per species
What is abundance?
The variable that goes on the y-axis.
What is the dependent variable?
When you give an account of an event, pattern or process, or of the characteristics or features of something.
What is describe?
Aspects of the environment which restrict the growth, abundance and distribution of a species.
What are Limiting Factors?
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?
A group of organisms that is believed to comprise a common ancestor and all of its evolutionary descendants.
What is a clade?
Examples include dissolved oxygen, light intensity, temperature, depth, humidity, pH and wind speed.
What are abiotic factors?
When you establish, conclude or ascertain after consideration, observation, investigation or calculation; decide or come to a resolution.
What is determine?
This refers to the proportional representation of different species within a particular ecosystem or community.
What is relative species abundance (or species evenness)?
By doing this, fragile areas can be protected and land clearing prevented. It also enables an understanding of species diversity and the management of natural resources in a sustainable manner.
What is ecosystem classification?
A biological community of interacting organisms and their physical environment.
What is an ecosystem?
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?
When you arrange, distribute or order in classes or categories according to shared qualities or characteristics.
What is classify?
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?
1. Any group of organisms are related by descent from a common ancestor.
2. New organisms arise when existing populations divide into two groups.
3. Changes in characteristics occur in lineages over time.
What are the three assumptions that underpin cladistics?
The graded organisation that groups things in levels from general to very specific subgroups.
What is hierarchical?
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?
When you display recognition of similarities and differences and recognise the significance of these similarities and differences.
What is compare?
