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.
