Study Notes
Ecology
- Ecology is the study of how organisms interact with their environment and each other.
Population
- A population is a group of the same species living in a specific area at a given time, who can interbreed and interact.
Community
- A community encompasses all the organisms in a given area.
Ecosystem
- An ecosystem includes all organisms and the non-living (abiotic) factors in a particular area.
Abiotic Factors
- Abiotic factors are non-living aspects of the environment. Examples include temperature, water, sunlight, wind, rocks, and soil.
Biotic Factors
- Biotic factors are living components of an ecosystem, and include interactions like predator-prey relationships, parasite-host relationships, and other organism-organism interactions. Examples are birds, insects, predators, prey, and parasites.
Biosphere
- The biosphere is the global ecosystem.
Niche
- An organism's niche includes its feeding habits and the conditions it needs to survive.
Latitude and Altitudes
- Latitude describes horizontal position on the Earth, with the equator as the lowest latitude and the poles as the highest.
- Altitude describes vertical position and the range of elevation.
Density-Dependent Factors
- Density-dependent factors influence populations based on their size. Examples include predation, famine, diseases, and toxic waste.
Density-Independent Factors
- Density-independent factors affect a population regardless of its size. Examples include volcanoes, forest fires, floods, and earthquakes.
