Study Notes
Global Warming and Climate
- The main culprit for global warming is the increasing levels of carbon dioxide and other greenhouse gases in the atmosphere.
- The main contributors to the increasing temperature on Earth are the increasing levels of carbon dioxide and other greenhouse gases in the atmosphere.
Carbon Sinks
- Natural carbon sinks include oceans, forests, and soil.
Plant Biology
- Water is transported within plants through the process of transpiration, in which water absorbed by plant roots is transported up the plant and evaporates through pores in the leaves.
Ecology
- A population in ecology refers to a group of individuals of the same species that live in a specific geographic area.
- The level of ecological research that includes all the populations of a given area is known as a community.
- Abiotic factors in an ecosystem refer to non-living components, such as temperature, water, sunlight, and soil.
- The type of ecosystem, whether it's desert, tropical, temperate, boreal, or polar, is determined by the climate of the region.
- The study of ecology involves collecting and analyzing data on the relationships between organisms and their environment.
Climate and Weather
- Climate refers to long-term average atmospheric conditions in a particular region, while weather refers to short-term atmospheric conditions.
Global Cycles
- Global cycles in ecology involve the movement of nutrients, water, and other resources within and between ecosystems.
