Bell Work

• Draw a food chain using the following organisms, and label each as a producer, primary consumer, secondary consumer, and tertiary consumer.• Rabbit• Fox• Carrot• Cougar

• Where does energy start for every food chain?

Carbon CyclePhotosynthesis and Cellular Respiration

The Carbon Cycle

• The carbon cycle is the process by which carbon moves though the planet in its different forms.• It exists in an ecosystem in two main forms:• Organic (plant/animal material, sugars, fats…)• Inorganic (carbon dioxide, limestone rock)

Plants and Animals

• Plants and animals rely on one another for survival.

• Can you think of a way plants rely on animals?• Can you think of a way animals rely on plants?

Plants and Photosynthesis

• Plants remove carbon from the atmosphere• Carbon in the atmosphere exists as carbon dioxide (CO2)• Plants take in carbon dioxide and use it to create glucose and oxygen

Water + Carbon Dioxide + Energy glucose + oxygenFrom the sun

Animals and Cellular Respiration

• Animals release carbon into the atmosphere in the form of CO2

• They do so by the process of cellular respiration

Glucose + oxygen energy + carbon dioxide + water

What do you notice?

water + carbon Dioxide + energy glucose + oxygen

Glucose + oxygen energy + carbon dioxide + water
