Introduction to Ecosystems

Learning OBJECTIVES: • To understand the nature

and scale of ecosystems• To learn about different

ecosystems processes Learning OUTCOMES:All will be able to identify an

ecosystemMost will be able to know the

differences between ecosystems

Some will be able to give named examples of ecosystems

Define: say what something means.Give examples: use real life

examples.State: provide an answer from

recall.Explain: give reasons why/how something has changed or is

changing.

Big Questions: What is an ecosystem?

EcosystemsAn ecosystem is a

natural system made up of plants, animals and the environment

Big Question: What is an ecosystem?

The components of an ecosystem are categorised as either biotic or abiotic.

Biotic = livingAbiotic = non-living

Ecosystems can be as huge as a rainforest.

Or as small as a puddle.

Ecosystems can vary hugely in size and scale…

Big Question: What is an ecosystem?

Ecosystems- the way that all the living and non-living parts of an environment interact.

Ecosystems can be from the very small to the very large!! Some examples of ecosystems are below:

A garden pond

A pool of water caught in the leaves of a plant. The Amazon

Rainforest

A small lake

A large UK woodland

Antarctica

A small flowering plant

What is a Food Web?Big Question: What is an ecosystem?

= shows lots of food chains and how they overlap= shows how energy and nutrients move around an

ecosystem

Nutrient Cycling

➢ Dead material decomposes➢ Nutrients are released➢ Nutrients are taken up by plants➢ Plants eaten by consumers➢ Consumers die and decompose➢ Cycle repeats…

Gersmehl Diagrams

Different sized circles = stores of nutrients within biomass, litter and soil.

Arrows of varying thickness = nutrient transfers, inputs and outputs
