Community

A community is a group of different populations of organisms that live and interact with each other in a particular area. It includes all living things in an ecosystem and the interactions among them.

Types of Communities

Communities can be classified based on different factors such as the type of environment they are found in, the species present, and their size. Some common types of communities include:

Terrestrial Communities: Found on land and include forests, grasslands, deserts, and more.
Aquatic Communities: Found in water bodies such as oceans, rivers, lakes, and ponds.
Urban Communities: Found in human-inhabited areas such as cities and towns.

Components of a Community

A community consists of various components, including:

Population: A group of individuals of the same species living in the same area.
Habitat: The specific environment in which a community lives, including both biotic and abiotic factors.
Interactions: The relationships and interactions between different species in the community, such as predation, competition, and mutualism.

Study Guide

Here are some key points to remember when studying the topic of community:

Define the term "community" and explain its significance in ecology.
Identify and describe the different types of communities based on their location and the species present.
Understand the components of a community, including populations, habitats, and interactions.
Explore the various interactions that occur within a community and their impact on the ecosystem.
Compare and contrast terrestrial, aquatic, and urban communities, noting their similarities and differences.
Discuss the importance of preserving and conserving communities for the well-being of the environment and all living organisms.

By understanding the concept of community and its role in ecology, we can gain a deeper appreciation for the interconnectedness of all living things in nature.

Our impact on earth

The resources above cover the following skills:

EARTH AND SPACE SCIENCE

Earth’s Systems

Analyze and interpret data (e.g., tables, graphs, maps of global and regional temperatures; atmospheric levels of gases such as carbon dioxide and methane; rates of human activities) to describe how various human activities (e.g., use of fossil fuels, creation of urban heat islands, agricultural practices) and natural processes (e.g., solar radiation, greenhouse effect, volcanic activity) may cause changes in local and global temperatures over time.

Earth and Human Activity

Analyze evidence (e.g., databases on human populations, rates of consumption of food and other natural resources) to explain how changes in human population, per capita consumption of natural resources, and other human activities (e.g., land use, resource development, water and air pollution, urbanization) affect Earth’s systems.

Implement scientific principles to design processes for monitoring and minimizing human impact on the environment (e.g., water usage, including withdrawal of water from streams and aquifers or construction of dams and levees; land usage, including urban development, agriculture, or removal of wetlands; pollution of air, water, and land).
