biodiversity
organism
is any living thing, from tiny bacteria to humans and animals.
What are the properties of life?
- Metabolism
- Growth & Development
- Reproduction
- Response to Stimuli
- Homeostasis
- Adaptation & Evolution
ecology.
the study of how organisms interact with each other and their environment.
What is the origin of the word ‘ecology’?
comes from the Greek word ‘oikos’, meaning house.
Everything is connected to everything else.
What is the first of Barry Commoner’s 4 Laws of Ecology?

What is the definition of biodiversity?
Biodiversity means the variety of life on Earth, including different species, genes, and ecosystems.
Break down the word ‘biodiversity’.
- ‘Bio’ = Life
- ‘Diversity’ = Variety
What are the four components of biodiversity?
- Genetic Diversity
- Species Diversity
- Ecosystem Diversity
- Functional Diversity
What is genetic diversity?
Genetic diversity is the variety of genes within a species.
What is species diversity?
Species diversity is the number of different species in an area.
What does ecosystem diversity refer to?
Ecosystem diversity refers to the variety of ecosystems on Earth.
Define functional diversity.
Functional diversity is the different roles species play in nature.
How is biodiversity measured?
- Species Richness
- Species Evenness
- Species Abundance
What is species richness?
Species richness is the number of species in an area.
What does species evenness measure?
Species evenness measures how evenly species are distributed.
Define species abundance.
Species abundance is the total number of individuals of one species in an area.
What are abiotic components?
Abiotic components are non-living factors that affect biodiversity.
List the abiotic factors affecting biodiversity.
- Temperature
- Water
- Soil
- Sunlight
- Air
What are biotic components?
Biotic components are living factors in an ecosystem.
List the types of biotic components.
- Producers (Plants)
- Consumers (Animals)
- Decomposers (Fungi & Bacteria)
What is the summary of biodiversity?
Biodiversity is the variety of life, including different genes, species, and ecosystems.
