Key Concepts
What does Yield mean?
The amount of crop produced per unit of land (e.g. Kilograms per hectare).
What process do plants undergo when exposed to sunlight?
Photosynthesis
What does 'GMO' mean?
Genetically Modified Organism
What does Scarcity mean?
Limited availability compared to the wants and needs of people.
How does temperature influence where crops can be grown?
Different crops need certain temperature ranges to grow. If it's too hot or too cold, the plants might not survive or produce food properly.
Increase crop yields (Produce more food on the same land).
Make crops resistant to pests and diseases, reducing the need for pesticides.
Improve tolerance to environmental stress like drought, salinity, or extreme temperatures.
Enhance nutritional value (e.g. Golden rice with Vitamin A
What is Biotic and Abiotic?
Biotic - Living organisms that affect ecosystems
Abiotic - Non-living components that influence living organisms.
Crops are vulnerable to high temperatures, especially if hot days occur when they are....?
Flowering
What is the purpose of 'Vertical Farming'?
Instead of using soil and sunlight, the plants grow in water with nutrients (called hydroponics) and use artificial lights.
Why is soil important for agriculture?
oil is important for crops because it provides support and nutrients. Soil gives structural support to plants so they can grow. It also feeds the plants as fertile soil is important for providing essential nutrients.
what are two reasons why bees are important to our ecosystem?
Pollination of Crops, Support Biodiversity, Food for Other Species, Seed Production and Plant Growth, Economic Impact, Environmental Health Indicators.
Name 4 modern technologies used in Agriculture
Mechanisation (tractors, harvesters)
Irrigation systems (drip, pivot)
Drones (monitoring crops, spraying)
Precision agriculture (GPS tracking, soil sensors)
GMOs (genetically modified crops)
Apps & farm management software (Autonomous Tractors
What are the environmental characteristics of 'El Nino'?
Hot, dry and less rain (drought)
Broccoli grows well in what climates?
Mild temperature climates
What is 1 pro and 1 con of using drones in agriculture?
Pros
Increases yield through early action
Saves time and rescues labour costs
Reduces chemical use
Cons
May not suit the needs of small-medium scale farms
Expensive initially to buy, and to maintain
Need training to use it, and has to be the right conditions
