​Producers

​Organisms that can make food are very important in the ecosystem. They can produce food for themselves, and the others that eat them.

Multiple Choice

What is another term for a producer?

• Autotroph

• Heterotroph

• Herbivore

• Carnivore

​Chloroplasts

​Plant cells have a unique organelle called a chloroplast. Chloroplasts contain a pigment called chlorophyll, which is what absorbs solar energy so the plant can use it to make food.

Draw

Circle the part of the plant that does photosynthesis.

​Chemical Reactions

​​Photosynthesis is an example of a chemical reaction.

​

Reactants are the original molecules that go into the reaction. They are rearranged and used to make products, which is what comes out of the reaction.

Multiple Select

Select the reactants of photosynthesis

• Carbon Dioxide

• Oxygen

• Water

• Glucose

• Solar Energy

Multiple Select

Select the products of photosynthesis

• Carbon Dioxide

• Oxygen

• Water

• Glucose

• Solar Energy

​My Mommy <3

​This is my mom, Flor. Her name means "flower" in Spanish- and she really does love flowers!

​

​She talks and sings to her plants as she waters them, and she insists it helps them grow better.

Poll

Do you think you talking and singing to plants a lot helps them grow?

• I think so

• No, I don't think so

​Some people say talking to plants helps them grow because you are giving them more CO2 as you exhale more around them!

Multiple Choice

True or False:

Photosynthesis can not take place if there is no sunlight

• True

• False

​Oceans & Oxygen Availability

​​There are organisms like animals found all over the planet, even in the deep ocean and they need oxygen to survive.

​

​Examine the information on the following slide. It is a chart that examines the relationship between the depth of the ocean and the amount of oxygen available.

​​Examine the chart- what seems to be happening to the amount of oxygen the deeper you go into the ocean?

Open Ended

​Examine the chart- what seems to be happening to the amount of oxygen the deeper you go into the ocean?

The Aphotic Zone

​The word "photo" means light.

​

​Like in photosynthesis, where plants can use light to create sugar.

​

​If we say there is an aphotic zone in the oceans, what do you think this means?

Dropdown

I think aphotic means ​

Select answer

.

Multiple Choice

True or False: Plants can survive in the aphotic zones of the ocean

• True

• False

There are no plants in the aphotic zones of the ocean.

​Plants can not survive in the aphotic zones

​There is no sunlight, so there are no plants and no photosynthesis in the deep ocean zones.

​

​For a long time, scientists thought this means there was no life in the deep oceans.

​

​Until 1977- enter Robert Ballard and his expedition to the ocean floor.

​In 1977, Robert Ballard was the first scientist to discover there was life on the ocean floor. BUT- there are very different kinds of producers living in the deep ocean.

Multiple Choice

Do you think deep ocean producers can do photosynthesis?

• Yes they can

• No they can't

​Chemosynthesis

​There is no sunlight, so there are no plants or photosynthesis in the deep ocean.

​

​The main kinds of producers are bacteria that do chemosynthesis, where they use chemicals released from the Earth to help them create sugar.
