Aerobic Respiration glucose + oxygen → carbon dioxide + water+ energy

Photosynthesis is how a plant makes its own food. Above is a plant cell, the chloroplasts contain chlorophyll which carry out photosynthesis. The word equation is: Water + Carbon dioxide Sunlight and Chlorophyll

Glucose (stored as starch for energy) + Oxygen

Fermentation Fermentation is when some microorganisms like fungi (yeast) respire anaerobically when there is a lack of oxygen available to them. Instead of producing lactic acid like humans and other animals they produce ethanol instead. Glucose  Ethanol + Carbon dioxide

Respiration is a chemical reaction that produces energy from glucose, so we can function. It happens inside living animals’ cells in the MITOCHONDRIA. NOTE: NOT THE SAME AS BREATHING!!

Anaerobic Respiration glucose → Lactic acid + energy

Anaerobic respiration is the other type of respiration that occurs when we do not have enough oxygen in our bodies but still need energy. Lactic acid is what is produced in your muscles when you get a CRAMP. Oxygen debt – the amount of oxygen we breathe in after exercise to break down lactic acid. Recovery time – the time it takes to get back to the normal resting heart rate.

Key words Photosynthesis, Starch, Xylem, Phloem, Chlorophyll, Chloroplasts, Aerobic, Anaerobic, Respiration, Glucose, Mitochondria, Lactic Acid, Oxygen Debt, Alveoli, Diffusion, Fermentation.

A pyramid of numbers is represented by different shaped rectangles as shown on the right. With the producer at the bottom of the pyramid and going along the food chain as you get higher.

Classification means to put things into groups. We can group living organisms into these 7 subgroups.  Below are some examples of how a camel is adapted to its habitat.

A food chain shows what eats what with the arrows pointing to the consumer. Just imagine whatever is at the beginning of the arrow goes in the mouth of what the arrow is pointing at!

You can use this to help you remember them: King Phillip Came Over From Great Spain

A contaminant is something that is toxic/foreign to an organism’s body. These can include: plastics (nurdles), mercury, oil, etc. These can be passed up the food chain which is why we should worry as we are at the top!

Decomposition can be slowed down or stopped by: • Freezing • Chilling/Cooling • Canning • Adding salt/sugar • Adding vinegar Key words

Producers Primary Consumers Secondary Consumers Trophic levels

Organisms that make their own food. Organisms that consume producers. Organisms that prey on primary consumers. This is the number of steps from the start of the food chain an organism is on. A pyramid shape that shows the organisms in a food chain by their biomass (dried weight). A pyramid shape that shows the organisms in a food chain by how many there are in a habitat. An organism that breaks down the remains of another organism. To maintain something in its original state. Something related to or comes from living matter. Features that allow an organism to survive in their habitat. Somewhere an organism lives. Changes over time that help something develop. A non-renewable substance made of fossils that can be burnt to produce energy. When sulphur dioxide dissolves in water(in clouds) and falls as sulphuric acid. The warming of the earth's atmosphere and oceans from carbon dioxide release.
