What is the primary reason for the significant decrease in the euchroma beetle population due to deforestation?
What is the primary reason for the significant decrease in the euchroma beetle population due to deforestation?
- Deforestation improves the beetle's mating environment.
- Deforestation has no impact on beetles.
- Deforestation creates more food sources for larvae.
- Deforestation destroys the mating habitat and food sources. (correct)
Which of the following actions would be the most effective in addressing rising carbon dioxide levels?
Which of the following actions would be the most effective in addressing rising carbon dioxide levels?
- Increase industrial emissions while planting trees.
- Increase the use of fossil fuels to enhance growth.
- Plant more trees and reduce deforestation. (correct)
- Stop all human activities that emit carbon dioxide.
Based on an experiment comparing rainwater and tap water, what conclusion can be drawn?
Based on an experiment comparing rainwater and tap water, what conclusion can be drawn?
- Both types of water have no effect on plant growth.
- Rainwater may support better plant growth due to fewer chemicals. (correct)
- Tap water enhances plant growth compared to rainwater.
- The growth difference is due to soil type, not water type.

Flashcards
Deforestation's impact on beetles
Deforestation's impact on beetles
Deforestation destroys beetle mating habitats and reduces food sources, leading to population decline.
Solution to carbon dioxide increase
Solution to carbon dioxide increase
Planting more trees and reducing deforestation helps absorb excess carbon dioxide.
Rainwater vs. tap water plant growth
Rainwater vs. tap water plant growth
Plants watered with rainwater grew slightly better than those with tap water, suggesting tap water chemicals may inhibit growth.

Study Notes
Beetle Growth & Deforestation
- Deforestation negatively impacts beetle populations.
- Prediction B (a large decrease) is more accurate than prediction A (slight decrease) due to habitat destruction & fewer food sources.
Carbon Dioxide & Solutions
- Planting more trees and reducing deforestation can absorb more carbon dioxide.
Plant Growth & Water Types
- Rainwater-fed plants experienced slightly better growth than tap water-fed plants during a two-week period.
- Tap water likely contains chemicals that limit plant growth.
Greenhouse Gas Emission Reduction
- Increasing use of mass transit can reduce carbon dioxide emissions.
Environmental Disturbances
- A significant, short-term change or event in an environment is called a disturbance.
Plant Adaptations
- The green color of leaves, due to chlorophyll, allows for photosynthesis – this isn't an incorrect adaptation, but rather a fundamental process.
Invasive Species & Rat Control
- Introducing non-native predators (cats) to control a pest population (rats) can lead to an uncontrolled increase in the predator population if they lack natural predators themselves.
Sheepshead Fish & Temperature Changes
- Sheepshead fish can tolerate a temperature decrease from 24°C to 6°C, and would therefore survive the change.
Human Impact Solutions
- Recognizing the irreversible consequences of resource depletion is key to reducing human impact on the environment.
Population Dynamics & Wolf Populations
- Increased moose populations can lead to a rise in wolf population.
