UNIT 11: ECOLOGY AND HUMAN IMPACT
UNIT 11: ECOLOGY AND HUMAN IMPACT
THE FINAL UNIT IN BIOLOGY HAS COME UP FAST! IN THIS UNIT WE WILL STUDY HOW ORGANISMS INTERACT WITH EACH OTHER AND THEIR ENVIRONMENT, AND WHAT STRUCTURAL, BEHAVIORAL, AND REPRODUCTIVE ADAPTATIONS SPECIFIC ANIMALS AND PLANTS HAVE ACQUIRED TO BETTER ADAPT TO THEIR ENVIRONMENT. WE WILL CONCLUDE THE UNIT AND THE SEMESTER WITH A FOCUS ON HOW HUMANS IMPACT THE ENVIRONMENT AND THE NUTRIENT AND WATER CYCLES.

Living systems require a continuous input of energy to maintain organization. The input of radiant energy which is converted to chemical energy allows organisms to carry out life processes.
Living systems require a continuous input of energy to maintain organization. The input of radiant energy which is converted to chemical energy allows organisms to carry out life processes.
Within ecosystems energy flows from the radiant energy of the sun through producers and consumers as chemical energy that is ultimately transformed into heat energy. Continual refueling of radiant energy is required by ecosystems.
