- Farming Practices to Increase Productivity
- Plants
- Pesticides and biological control
- Fewer predators means more ability to photosynthesise (more living plant tissue)
- However, it can decrease biodiversity and endangers the natural food chain
- Antibiotics
- Lowers the risk of plants becoming diseased
- Less energy is wasted on fighting disease
- However, it can lead to immune bacteria
- Herbicides
- There is a lack of competition
- This means that there are more nutrients for the species
- e.g. nitrates for growth, phosphates for ATP/DNA/ phospholipids
- However, it can lead to a decrease in biodiversity
- Fertiliser
- More specific nutrients for the plant
- The plant is getting the exact nutrients it needs
- e.g. magnesium for the chlorophyll, potassium for cell turgidity
- But, it can lead to eutrophication and the destruction of habitats
- Pesticides and biological control
- Animals
- Reduce movement
- Lowers the need for ATP and therefore, for respiration
- Reduces respiratory losses
- However, it can lead to boredom and an increased risk of disease
- High energy diet
- More food can be easily assimilated
- Therefore, less energy is wasted on creating excretory products
- However, fast-tracked development can lead to a weak skeletal structure
- Antibiotics
- Lowers the risk of livestock becoming ill
- Less energy is wasted on fighting disease
- However, it can lead to immune bacteria
- Selective breeding
- Choose traits of offspring based on parents
- Desired traits are more likely to show - strongest female + strongest male = stronger offspring
- Sometimes the desired traits are not shown - months wasted on bad result
- Reduce movement
- All of these practices reduce energy loss so more energy can be converted into biomass
- Plants
