This document defines key terms related to ecology and environmental science. It explains that the environment consists of abiotic and biotic factors. An organism is any living thing, and a species is a group that can interbreed. A population is a group of the same species in an area, while a community includes all living things in a region. An ecosystem is the complex of communities and environment in an area. The document also defines ecotones, biomes, and asks questions about ethics.

CHAPTER 2: THE ENVIRONMENT AND ORGANISM REGIE L. MAGALLANES, LPT, M.ED Environmental Science - Instructor
ECOLOGY The study of the relations ships between organisms and between organisms and their environment.
WHAT DO YOU MEAN ENVIRONMENT? The environment is made up of two things 1. Abiotic Factors: Non-living (never was living) Examples: rocks, water, air, weather, sunlight, sand, and temperature. 2. Biotic Factors: Living ,once living things or part of a living organism. Examples: Leaves, trees, poop, whales, flowers, mushrooms.
ORGANISM • Any unicellular or multicellular form exhibiting all the characteristics of life, an individual • • The lowest level of organization in ecology

POPULATION • A group of individuals of the same species that live in a given area and interbreed. Example: Wolves of Yellow Stone Park, The ants at AISE, Plumeria’s in Cairo.
POPULATION VS. SPECIES • Population vs. Species: Gray wolves of Yellowstone park vs. gray wolves of the world.
BIOTIC COMMUNITY (BIOTA) • All the living organisms that live in a particular area. • Includes vegetation to animals to microscopic creatures such as bacteria.
ECOSYSTEMS • An interactive complex of the communities and the abiotic environment affecting them within a particular area.
ECOTONES AND BIOMES Ecotone: The transition area between two ecosystems. Share’s many characteristics between both ecosystems. Biome: a large area of Earth’s surface with the same climate and similar vegetation. Examples: Tropical rainforest, tundra, grasslands, deserts
QUESTION? 1. Which Foci of ethics do you most agree with? 2. What counts as an ethical action, does it always agree with science / economy? 3. If not, then what weighs or decides which action to be taken?
THANK YOU!
