Study Notes

Predator-Prey Dynamics

An increase in predator numbers can lead to a decrease in prey populations if prey fail to reproduce quickly enough.
This decrease in prey results in heightened competition among predators for food, eventually leading to a decline in predator populations.

Classification of Organism Relationships

Organism relationships can be categorized into three broad classes.
Examples include:
- Flowering plants providing food and shelter to pollinators.
- Habitat loss impacting wildlife and contributing to biodiversity decline.

Environmental Impact of Land Clearing

Slash-and-burn land clearing techniques contribute to greenhouse gas emissions, exacerbating climate change and causing haze.

Waste Management Challenges

Excessive consumption generates waste that can lead to significant air, land, and water pollution.
Burning electronic waste increases electrical consumption and greenhouse gas emissions from burning fossil fuels.

Conservation Principles

Conservation involves the protection and preservation of Earth's natural resources, emphasizing sustainable usage aligned with current needs.

Strategies for Environmental Conservation

Techniques to conserve the environment include utilizing apid principles, such as employing plants, which can reduce nutrient loss from the soil and improve growth conditions.
