[18] Food Production

what are glasshouses and polythene tunnels used for?

to provide protection for crops and an enclosed environment in which the grower can control the climate inside to some extent.

what does an increase in temperature do to yield and why when growing plants? what happens if temperature gets too high

can increase yield when growing plants because it speeds up enzyme activity, leading to faster photosynthesis and plant growth.

If the temperature gets too high, enzymes can denature, slowing down photosynthesis and reducing yield.

what does an increase in carbon dioxide do to yield and why when growing plants

can increase yield when growing plants because CO₂ is a reactant in photosynthesis.

More CO₂ allows plants to produce more glucose, leading to faster growth and higher crop yields

what do fertilisers do

fertilisers provide essential nutrients, such as nitrogen, phosphorus, and potassium, to plants increasing crop yields

what are advantages of using pesticides

• increases crop yield by protecting plants from pests that cause damage by killing them.

• They also help prevent the spread of diseases leading to healthier crops. which improves the yield of crops

what are alternatives to pesticides

biological control where predators are introduced to control pest populations, which prevents pests harming plants being grown

what are the disadvantages of pesticides

when present in big enough numbers, they cause economic damage as the increase in higher yields causes an increase in income.

they cause environmental damage as they kill other insects that are harmless and helpful species such as bees

what do pesticides kill

herbicides
insecticides
fungicides
molluscicides
