N5 3.5 Food Production Flashcards

Front

Food yield

Back

How much food is produced in a given time

Front

Nitrates

Back

can be added to soil in fertilisers to increase crop yield.

nitrates are required by plants for making amino acids which are used to form proteins.

Front

Amino acids

Back

join together to form Proteins

Front

Protein synthesis

Back

process carried out in cells for making proteins from amino acids.

takes place in Ribosomes.

Front

What do consumers eat to gain the amino acids needed for protein synthesis?

Back

Plants or other animals

Front

Leaching

Back

The process of fertilisers being washed from fields into water supplies.

Front

Algal Bloom

Back

forms when small water plants called algae increase rapidly in number (usually caused by excess fertilisers leaching into rivers/lochs)

Front

What can cause an algal bloom in rivers and lochs?

Back

Excess nitrates from fertilisers, which leach into the rivers and lochs

Front

What happens when an Algal Bloom forms as a result of fertiliser leaching into rivers/lochs.

Back

1.Algae population increases forming an algal bloom.

2.Light levels are reduced which kills aquatic plants.

3.Bacteria feed on dead plants

4.Bacteria increase in number and use up lots of oxygen which results in other organisms being unable to survive.

Front

Pest

Back

A destructive insect or other animal that attacks crops, food, livestock, etc.
