What is the following statement describing? A situation where numbers of living organisms remain roughly constant over time.

Communities

Identify examples of interdependence within an ecosystem

Predict the impact of changes to one species on the rest of the community

Extract and interpret information from charts, tables and graphs relating to interaction of organisms in a community

This lesson introduces the topic of ecology and looks at communities and how organisms interact.

Case Study: Dr Beth Penrose

What type of organism is always found in trophic level 1?

Revision: what do the arrows in a food chain show us?

What is described as the mass of living organisms?

In a food chain 200 kg of wheat is fed on by 18 kg of mice which in turn are eaten by 1kg of hawk. What is the percentage energy transferred from the first trophic level to the third?

What is the best description of food security?

Select two reasons why some populations might have poor food security.

Revision: Select two reasons why biomass is lost between the trophic levels of a food chain.

What is sustainable fishing?

Revision: Which is the example of a behavioural adaptation?

Why is decay a useful process?

Select the two main types of organisms involved in decay.

Which condition from the list will help decay to occur?

Select three key features of a compost bin.

Revision: what do all food chains and webs start with?

What is the definition of a biotic factor?

What effect would a constantly low temperature have on a population of plants?

What is a structural adaptation?

Why do desert plants tend to have spines rather than large leaves?

Revision: what is an apex predator?

Which is an effect of global warming?

Revision: select the three ideal conditions for decay.

In the following food chain which organism is the apex predator? Mahogany tree → caterpillar → song bird → hawk

Which resources do plants compete for?

How do we reduce bias in a sampling experiment?

What is a functional adaptation?

Select three things that can be done to help maintain biodiversity.

Revision: what is a quadrat?

An animal has a surface area of 120,000 cm² and a volume of 40,000 cm³. What is the surface area : volume ratio?

What is the area of a quadrat with a side length of 0.4 m?

A field has an area of 765 m². A 0.5 m x 0.5 m quadrat was placed 8 times and the number of buttercups counted as follows 22, 10, 6, 8, 0, 11, 9, 17. Estimate the population of buttercups in the field.
