1. What is Ecology?

Ecology is the scientific study of the interactions between living organisms and their environment. This includes the study of how plants, animals, and microorganisms interact with each other and with their surroundings, as well as how they depend on each other for survival. Understanding ecology is important for conserving the Earth's biodiversity and ensuring the sustainability of natural ecosystems.



2. Important Concepts in Ecology

Some of the key concepts that students should be familiar with in order to do well in their Leaving Cert Ecology exams include:

  1. Niche: This refers to the specific role and position that a species occupies in its ecosystem.

  2. Population: A population is a group of individuals of the same species that live in the same area.

  3. Community: A community is a group of populations of different species that live and interact in the same area.

  4. Habitat: This is the natural environment where an organism lives and thrives.

  5. Ecosystem: An ecosystem is a community of living organisms and their physical environment.

  6. Biotic factors: These are the living components of an ecosystem, such as plants, animals, and microorganisms.

  7. Abiotic factors: These are the non-living components of an ecosystem, such as temperature, sunlight, and soil type.

  8. Food chain: This is a series of organisms in which each organism is eaten by the next organism in the series.

  9. Food web: This is a complex network of interconnected food chains in an ecosystem.

  10. Symbiosis: This is a relationship between two different species in which both species benefit from the interaction.

  11. Succession: This is the process by which the species composition of a community changes over time.
