All Flashcards
Why are bees important?
Crucial pollinators for many crops; declining bee populations are a major environmental concern.
Explain pesticide resistance.
Pests develop tolerances to pesticides, requiring increased usage and costs.
What is the impact of pesticides on food chains?
Pesticides can disrupt food chains by harming or killing organisms, leading to imbalances in the ecosystem.
How do pesticides affect biodiversity?
Pesticides can reduce biodiversity by harming non-target species and disrupting ecological relationships.
What are the human health risks of pesticide exposure?
Pesticide exposure is linked to cancer, birth defects, and neurological problems.
Explain the concept of toxicity in relation to pesticides.
Pesticides can be harmful to non-target species, including birds, bees, mammals, and aquatic life.
Describe the role of pesticide regulations.
Laws and policies designed to control pesticide use and minimize their negative impacts on the environment and human health.
What is the significance of pollinators?
Pollinators are essential for the reproduction of many plants, including crops, and their decline can have significant ecological and economic consequences.
Why is soil and water contamination a concern with pesticide use?
Pesticides can contaminate soil and water through runoff and leaching, affecting ecosystems and human health.
What are the benefits of disease control using pesticides?
Pesticides can protect against diseases like malaria and Lyme disease by controlling the pests that carry them.
What is the effect of insecticide use on bee populations?
Insecticide exposure leads to bee population collapse.
What is the effect of pesticide runoff?
Causes water contamination.
What is the effect of pests developing tolerance to pesticides?
Leads to increased pesticide usage and costs.
What is the effect of pesticides on non-target species?
Can harm or kill beneficial organisms like birds and bees.
What is the effect of pesticide leaching?
Causes soil contamination.
What is the effect of pesticide use on human health?
Linked to cancer, birth defects, and neurological problems.
What is the effect of pesticide use on food chains?
Pesticides can accumulate and magnify up the food chain.
What is the effect of pesticide use on soil quality?
Can degrade soil quality by harming beneficial organisms.
What is the effect of pesticide use on water quality?
Can contaminate water sources through runoff and leaching.
What is the effect of pesticide use on biodiversity?
Can reduce biodiversity by harming non-target species.
What are pesticides?
Substances used to control pests (plants, animals, fungi).
What are herbicides?
Pesticides that target plants (weeds, grasses).
What are fungicides?
Pesticides that control fungal infections in plants, seeds, or soil.
What are rodenticides?
Pesticides designed to kill rodents (mice, rats).
What are insecticides?
Pesticides that kill insects.
Define selective herbicide.
A herbicide that kills specific types of plants.
Define non-selective herbicide.
A herbicide that kills all types of plants.
What is bioaccumulation?
The accumulation of substances, such as pesticides, in an organism.
What is biomagnification?
The increasing concentration of a substance, such as a pesticide, in higher trophic levels of a food chain.
What is Integrated Pest Management (IPM)?
A sustainable approach to pest control that minimizes pesticide use.
