Irrigation
This term describes artificially supplying water to crops when rainfall is not enough.
What is Irrigation
These helpful insects are used as a sustainable strategy because they reduce aphid populations naturally.
What are ladybugs
This form of soil degradation occurs when wind, rain, or human activities like tilling or deforestation remove topsoil and reduce fertility.
What is erosion
Unlike traditional soil-based farming, this method grows plants using nutrient-rich water solutions and careful environmental control.
What is Hydroponics
This plant structure anchors the plant and absorbs water and minerals from the soil.
What are roots
Approximately this percentage of the world’s freshwater is used for agriculture.
What is 70%
This cultural practice improves soil health, increases biodiversity, and helps prevent pests by changing what crops are grown each season.
What is crop rotation
Soil compaction reduces pore spaces for air and water. Name one cause of this.
What is heavy machinery, livestock/foot traffic, tillage, or rainfall/lack of vegetation
What percent of grocery store items contain palm oil
What is about 50%
This green pigment inside chloroplasts captures sunlight so plants can make food.
Name one major negative consequence of poor irrigation, such as applying too much water or using inefficient methods.
What is erosion, water waste, soil salinization, runoff?
This widely used pesticide caused bird eggshell thinning, harmed wildlife, and led to regulatory bans.
What is DDT.
These natural barriers between land and water trap sediment, reduce runoff, protect aquatic habitats, and are important for sustainable land management.
What are riparian buffers
Peatland destruction for palm oil releases significant carbon emissions because peatlands are composed of this partially decomposed plant material that builds up in low-oxygen environments.
What is Peat
This vascular tissue moves water from the roots up through the plant.
What is the Xylem
What type of irrigation method would be most useful in a greenhouse setting?
What is localized irrigation
A farmer’s fields are experiencing rising pest resistance due to repeated chemical pesticide use. According to sustainable pest management principles, the farmer should redesign their system by combining biological, cultural, and mechanical controls. Name what this method is called and give one specific example of each control.
What is an IPM (Integrated Pest Management) and releasing lady bugs (biological), crop rotation, (cultural), and physical removal or barriers (mechanical).
What is one way farmers can reduce the chances of nutrient loss
Hydroponics eliminates the need for soil, but plants still require these substances (also found in soil) to perform essential processes like growth, photosynthesis, and enzyme function. Please list at least one major component
What is nutrients. (Nitrogen, Phosphorus, Potassium)
These tiny openings on the underside of leaves allow gases like carbon dioxide and oxygen to move in and out.
What are stomata.
In this surface irrigation method, water runs through shallow channels between rows of crops.
What is furrow irrigation
Overuse of pesticides allowed pests like the potato beetle to evolve this trait, making them much harder to control and requiring integrated pest management strategies.
What is pesticide resistance
What is one way that salinization can occur in the soil?
What is Poor Drainage or High Water Tables, Use of Salty Water for Irrigation, or Fertilizers and Road Salt
This system allows plants to grow in a vertical orientation.
What is a tower garden.
A plant’s stomata open to allow gas exchange. Explain why a plant might close its stomata during a hot, dry day and identify the trade-off this creates.
What is to prevent water loss through transpiration, but this reduces carbon dioxide intake and slows photosynthesis?
