Energy and Ecosystems

• Plants take in Carbon Dioxide​ & Sunlight energy to make food (sugar).

• Plants give off oxygen.

• Animals breath in oxygen and give off carbon dioxide.

• Most plants take in some oxygen as well.​

​Some text here about the topic of discussion.

​Green Machines

• ​Carbon Dioxide enters through tiny holes in plant leaves.

• ​Water from soil enters the plant through its roots

• Chloroplasts inside cells found in green parts of plant capture sunlight energy.

• Chlorophyll helps change CO2, water, & solar energy into sugar & O2​

Photosynthesis

• These organisms make their own food.

• Plants are the prime example

• Phytoplankton, whom live in oceans​, are also producers

Producers

• ​These organisms eat living things to get energy.

• Some eat only plants.

• Some eat only animals.

• Some eat both.​

Consumer​​

• ​Eat only producers.

• Common Herbivores: Mice, Rabbits, and Deer.​

Herbivores

• ​Eat only consumers.

• Common Carnivores: Lions, Penguins, and Ladybugs​

Carnivores

• ​Eat both producers and consumers.

• Common Omnivores:​ Humans, Box Turtles, and Toucan

Omnivores

• ​Canivores & omnivores that hunt and eat other animals.

Predator

• Animals that predators hunt.​​

​​Prey

• Predator and Prey populations are linked to each other.

• One population goes up, the other goes up.​

• One population goes down, the other goes down.​

• ​When plants and animals die, some organisms eat them for food.

  • ​These are called scavengers

  • Vulters, Polar Bears, Sharks

• Decomposers break down wastes and remains of dead organisms.

  • Returns nutrients to soil, air, & water.​

  • Bacteria are microscopic decomposers.

  • Fungi (mushrooms & mold)
