Ecology - Photosynthesis, Cellular Respiration and Toxins

Photosynthesis

The process plants use to convert sunlight into chemical energy in the form of glucose

Cellular respiration

The process of breaking down chemical energy into a useable form on energy

Word formula for photosynthesis

Carbon dioxide + Water + sunlight/chlorphyll —> glucose + oxegyn

Word formula for cellular respiration

Glucose + Oxegyn —> carbon dioxide + water + ATP energy

Chemical equation for photosynthesis

CO₂ + H₂O + Sunlight/Chlorophyll —> C₆H₁₂O₆ + O₂

Chemical equation for cellular respiration

C₆H₁₂O₆+ O₂ —> CO₂ + H₂O + ATP

Toxins

Poisonous chemicals passed along food chain

Bioaccumulation

The buildup of contaminants in an organism faster than it can remove them

Biomagnification

When the concentration of a chemical increases in the tissues of an organism as it travels up to higher ends of the food chain

POTs

persistent pollutants take a long time to break down

DDTS

insecticide that can cause reproduction issues, immune system issues and nervous system issues and make the shells of eggs weaker

PCB

Chemical used in lots of products like paints, plastics— interferes with immune functions
