ASSIGNMENT 3 CHAPTER 13.1 ECOLOGY Copy the text and all pictures. Underline vocabulary words.
MAIN IDEAS: • Ecologists study environments at different levels of organization.
Ecology is the study of the interactions among living things, and between living things and their surroundings. The place where a particular population of a
species lives is its habitat. The physical aspects of a habitat such as moisture, temperature, wind, sunlight, and soil. are called abiotic factors, and the living
organisms in a habitat are called biotic factors. Ecologists study nature on different levels, from a local to a global scale. These levels reveal the complex
relationships found in nature. 1. Organism An organism is an individual living thing, such as an alligator. •2. Population A population is a group of the
same species that lives in one area, such as all the alligators that live in a swamp. • 3. Community A community is a group of different species that live
together in one area, such as groups of alligators, turtles, birds, fish, and plants that live together in the Florida Everglades. •4. Ecosystem An ecosystem
includes all of the organisms as well as the climate, soil, water, rocks, and other nonliving things in a given area. Ecosystems can vary in size. An entire
ecosystem may live within a decaying log, which in turn may be part of a larger wetland ecosystem. Ecologists study relationships within each level of
organization and also between levels. For example, researchers may study the relationships within a population of alligators, as well as the relationships
between alligators and turtles in a community. The number of species living within an ecosystem is a measure of its biodiversity. An ecosystem includes both
biotic and abiotic factors. Changing one factor in an ecosystem can affect many other factors.
