Document Summary
Bagley l3: fundamentals of ecosystems mass: ecosystem. A self-sustaining biological system that consists of individual organisms, populations of organisms and communities of populations living together and interacting with each other and the surrounding environment: mass and energy are conserved in ecosystems. Bagley l4: fundamentals of ecosystems energy: 2nd law of thermodynamics. Bagley l6: energy flow through ecosystems: photoautotroph. Organisms that can convert light energy to chemical bond energy and convert carbon dioxide and other inorganic nutrients to organic molecules: heterotroph. Organisms that can only obtain energy for life from chemical bond energy. Bagley l5: food chains & bioaccumulation: food chain. Movement of energy from one trophic level to another: detrivores. Organisms that eat detritus (waste material), e. g. ; vultures, fungi, bacteria, etc: toxicity. There are two types of toxicity: acute toxicity. Responses include disease, loss of reproductive capability and sever mutations.
