Introduction To Ecology And Environmental Science

This course, Introduction to Ecology and Environmental Science, is a two-unit course that explores the inter-relationships of living organisms with each other and their environment. It examines the influences of abiotic and biotic factors on the growth, distribution, behavior, and survival of organisms. The course also covers biogeochemical cycles, basic environmental concepts, biotic communities, and ecological succession, providing a comprehensive understanding of ecological principles.

EHS202 · UNIT 1: BASICS OF ECOLOGY

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.

What you should be able to do

  1. Define and explain the basic principles of ecology.
  2. Describe the components and dynamics of ecosystems.
  3. Analyze the relationships between organisms and their environment.
  4. Evaluate the impact of human activities on ecological systems.
  5. Understand the processes of ecological succession and community development.

Where it gets hard

The units students slow down on, and what makes each one heavy.

  • Module 2: Basic Environmental Concepts and Theories

    Unit 1: Basic Environmental concept

    Understanding the nuances of Darwinian and Lamarckian theories requires critical analysis and comparison of evolutionary mechanisms.

Preparing for the exam

What to do
  • Review all Tutor-Marked Assignments (TMAs) and their feedback to identify areas of weakness.
  • Create concept maps linking key ecological concepts from Modules 1-3.
  • Practice defining key terms like 'ecosystem,' 'biome,' and 'succession' without referring to notes.
  • Focus on understanding the different types of ecological interactions (competition, predation, symbiosis) and their effects.
  • Allocate specific study time for each module, focusing on the learning outcomes provided in the course guide.
