Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Ecology The study of the interactions that take place among organisms and their environment Types of habitats Marine- oceans (salt water) Freshwater- lakes, rivers and ponds Terrestrial- Land: deserts, jungles, forests etc.

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Types of organisms Producers- organisms that produce their own food (plants) Photosynthesis- Chemical process where plants use sunlight to make glucose (sugar)

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Consumers: organisms that obtain energy by eating other organisms Herbivores: Obtain energy by eating just plants

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Carnivores Obtain energy by eating just meat (other animals)

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Omnivores Obtain energy by eating plants and animals

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Decomposers Obtain energy by consuming waste and dead organisms

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Interactions in ecosystems Predator/Prey- There is a hunter, and the hunted

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Food chain illustrates how consumers obtain energy from other organisms in an ecosystem

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Food web- a few food chains connected together The arrow points to what animal is receiving the energy For example, the fox receives its energy from rabbits, squirrels and mice

Topic: Ecology Essential Question: How do organisms interact in an ecosystem? Parasitism a symbiotic relationship in which one organism benefits but the other organism is harmed. Examples: Roundworms and dogs/cats: worm attaches to intestine and feeds on nutrients, animal can have pain, bloating diarrhea and possible death.

What to highlight You should not highlight everything, to start, you will highlight/underline what is in red. What we are highlighting will help us answer the essential question. How do organisms interact in an ecosystem?

Creating questions Look at what you’ve highlighted. What you have highlighted should be the answer to your question. We will do this together.
