A structural adaptation is [blank_start]a physical feature of an organism[blank_end] that enables the organism to better survive its environment

A behavioural adaptation is [blank_start]an action carried out by an organism[blank_end] that enables the organism to better survive its environment

A physiological adaptation is [blank_start]a process occurring within an organism[blank_end] that enables the organism to better survive its environment

When penguins huddle together for warmth, this is a behavioural adaptation.

Seed pods opening from the heat of bushfire is a behavioural adaptation

Penguins having different, individual calls is a structural adaptation

Check the following behavioural adaptations:

An adaptation enables an organism to [blank_start]better survive its environment[blank_end]

What is mutualism?

In parasitism, the [blank_start]host[blank_end] suffers while the [blank_start]parasite[blank_end] benefits.

Commensalism is an interaction where one organism benefits while the other is [blank_start]unaffected[blank_end]

[blank_start]Autotrophs[blank_end] use the sun or stored energy to make their own food, while [blank_start]heterotrophs[blank_end] depend on other organisms for food and energy.

heterotrophs are consumers

Check the examples of abiotic features

check the examples of biotic features:

Biotic is the living features of an environment

Abiotic is the living features of an environment

Examples of biological control are:

[blank_start]Herbivores[blank_end] eat only plants [blank_start]Carnivores[blank_end] eat mostly meat [blank_start]Omnivores[blank_end] eat both plants and meat

A [blank_start]predator[blank_end] kills other animals for food. The hunted animals are called [blank_start]prey[blank_end]. [blank_start]Scavengers[blank_end] will eat the remains of other animals, or attack sick or dying animals.

[blank_start]Decomposers[blank_end] break down/absorb waste and dead organisms

A producer is...

A consumer gets energy from eating other organisms

The trophic levels, in order, are: 1. [blank_start]Tertiary Consumers[blank_end] 2. [blank_start]Secondary Consumers[blank_end] 3. [blank_start]Primary Consumers[blank_end] 4. [blank_start]Producers[blank_end]

The arrows in food chains and webs show...

Biomass shows the combined mass of living organisms in a certain area
