a set of processes that transfer carbon between the atmosphere, organisms and Earth

the removal of trees, often to use the land for agriculture or building

having reliable access to enough safe and nutritious food to meet the needs of the human population

a set of processes that transfer water between the atmosphere, organisms and Earth

Deforestation affects the carbon and water cycles

Science

Pupils will learn about biomass transfer including calculating the efficiency of transfers between trophic levels. They will learn about human impacts on the environment, food security and biotechnology to help maintain biodiversity and achieve food security.

In the Climate change and greenhouse gases unit, pupils learnt about greenhouse gas emissions from transport and industry, and the use of renewable energy resources and changes to transport infrastructure that could reduce emissions.

In this unit pupils learn about the impact of agriculture and deforestation on biodiversity, and to more thoroughly consider the effects of climate change on biodiversity and food production.

Climate change and biodiversity

The diagram shows some important processes in the carbon cycle. Which process in trees and other producers uses carbon dioxide from the atmosphere to make biomass?

… has no effect on the amount of carbon in the atmosphere.

Jacob: We are left with fewer trees to absorb human emissions of CO$$_2$$.

Aisha: Deforestation increases the movement of carbon out of the atmosphere.

Who gives a correct reason why deforestation increases climate change?

The diagram shows some important processes in the water cycle. Which process moves water from the ground, through plants, and into the atmosphere?

True or false? Deforestation increases the amount of water absorbed into the ground, reducing the risk of flooding.

Legal protection against {{}} can maintain the essential role of forests in the water cycle and support our food security.

The removal of trees, often to use the land for farming or building, is called __________ .

Human activities cause emissions of a gas with the formula CO$$_2$$ into the atmosphere. The name of this gas is {{}} dioxide.

… both habitat loss and biodiversity loss.

… neither habitat loss nor biodiversity loss.

The diagram shows some important processes in the carbon cycle. Which process moves carbon from fossil fuels into the atmosphere?
