What is biodiversity? The variety of species of organisms that exist in one ecosystem. How does human development impact biodiversity? It usually results in reduced biodiversity due to habitat destruction. What is one impact of land development on ecosystems? Destruction of habitats, such as Peat Bogs, which reduces biodiversity. What is the effect of deforestation on ecosystems? It reduces biodiversity and releases CO2 when trees are burned. What does a pyramid of biomas...

Electron Microscope A microscope that fires electrons at objects and then creates a very detailed image. What 3 organelles do plant cells have that animal cells don't? what do they do? - Chloroplast - absorb light for photosynthesis - vacuole - stores cell sap - structure and support (keeps cell rigid) - Cell wall - made of cellulose - structure and support What are 4 key features of bacterial cells? - Small size - Cell wall - Cell membrane - loop of DNA (no nucleus) ...

What happens in photosynthesis and is it a endo or exothermic reaction Taking energy from light and locking it up in glucose. Endothermic reaction- takes in energy Requirements for photosynthesis Chlorophyll (the green pigment in leaves) Water Carbon dioxide Sunlight Effect of co2 on rate of photosynthesis (what it looks like on graph) Co2 increases rate of photosynthesis increases but only up to a point, then curves and straight Light intensity on photosynthesis (what it lo...

What are antibiotics? Drugs that kill or prevent the growth of bacteria without killing healthy body cells What is the problems with antibiotics? Bacteria can mutate and become resistant to an antibiotic How do bacteria make us feel ill?
