What is the main cause of eutrophication?
Excess nitrates and phosphates in water
Acid rain
Too much sunlight
Plastic waste
13.
In eutrophication, why does oxygen concentration fall?
Algae stop respiring
Fish use more oxygen
Water becomes warmer
Decomposer bacteria respire aerobically
14.
Which gas released by cattle contributes to global warming?
Nitrogen
Methane
Oxygen
Sulfur dioxide
15.
Which statement best describes Eutrophication?
The number of different species that live in an area.
Rearing large numbers of animals in a small space with controlled food and conditions to maximise output.
A gas such as carbon dioxide or methane that absorbs heat radiated from the Earth and contributes to global warming.
The process in which excess nutrients in water lead to algal growth, oxygen depletion and death of aquatic organisms.
16.
Which statement best describes Greenhouse gas?
The number of different species that live in an area.
A gas such as carbon dioxide or methane that absorbs heat radiated from the Earth and contributes to global warming.
Rearing large numbers of animals in a small space with controlled food and conditions to maximise output.
Growing a single crop species over a large area.
