1A - Ecology Flashcards
Energy Flow Ecosystems
Population
All of the individuals of the same species living within the same specific area at the same time.
Community
The sum of all the populations living in a particular area and their interactions
Ecosystem
All the living things in a particular area tigether with abiotic and biotic parts of that environment
Biosphere
Collection of all ecosystems representing the zones of life on earth -> litho, hydro, and atmosphere.
Ecology
The scientific study of interatctions between organisms and the environment.
Biological levels of organization, arranged from simplest to most complex.

Chemosynthesis formula
6CO2 + 6H20 + 3H2S -> C6H1206 + 3HSO4
Chemosynthesis
the process by which food is made by bacteria or other living things using chemicals as the energy source, typically in the absence of sunlight (bad ass photosynthesis)
Difference between Energy cycle vs Matter cycle
The energy cycle is an OPEN SYSTEM, it enters as sunlight and leaves as heat druing transfers between trophic levels.
The matter cycle is a CLOSED SYSTEM, it is recycled. Remember law of conservation mass: Energy cannot be created or destroyed, only transformed.
Producer/ Autotrophs
Organisms that synthesize its own food from inorganic molecules using chemical or light energy.
Conusumers/ Heterotrophs
Organisms that cannot make its own food through photo or chemosynthesis and must get their nutrients from organic molecules formed by producers.
Cellular respiration
a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
Cellular respiration formula
C6H12O6 + 6O2 –> 6CO2 + 6H2O + ATP
Photosynthesis formula
6CO2 + 6H2O → C6H12O6 + 6O2
Phoyosynthesis
the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
