Definition

A biological system is a complex network of biological components that work together to perform a specific function. These components can include cells, tissues, organs, and organisms.

Types of Biological Systems

Cellular Systems: These include the organelles and structures within a cell that carry out specific functions.
Organ Systems: For example, the respiratory system or the circulatory system.
Ecological Systems: These involve interactions between organisms and their environment, including ecosystems and food webs.

Key Concepts

Understanding biological systems involves knowledge of:

Cellular structures and functions
Physiology of different organ systems
Interactions between organisms and their environment
Energy flow and nutrient cycling in ecosystems

Study Tips

When studying biological systems, it is important to:

Review and understand the different cellular organelles and their functions
Learn the structure and function of major organ systems in the human body
Explore ecological concepts such as energy flow, trophic levels, and population dynamics
Practice drawing and interpreting diagrams to visualize biological systems

EARTH AND SPACE SCIENCE

Earth’s Systems

Construct an explanation from evidence for the processes that generate the transformation of rocks in Earth’s crust, including chemical composition of minerals and characteristics of sedimentary, igneous, and metamorphic rocks.

ENVIRONMENTAL SCIENCE

Earth and Human Activity

Engage in argument from evidence to defend how coastal, marine, and freshwater sources (e.g., estuaries, marshes, tidal pools, wetlands, beaches, inlets, rivers, lakes, oceans, coral reefs) support biodiversity, economic stability, and human recreation.
