This tortoise is eating cactus on a sunny day. Is carbon moving into the air, moving out of the air, or both?

• Carbon is not moving into the air; it is only moving out of the air.

• With this information, there is no way to know for sure.

• Carbon is only moving into the air; it is not moving out of the air.

• Carbon is moving into the air and out of the air at the same time.

Photosynthesis happens in the ​ (a)   They are organelles only found in ​ (b)   The sun's energy is drawn into the chloroplast to start the process of ​ (c)  

• chloroplast.

• producers.

• photosynthesis.

• mitochondria

• consumers

• decomposers

Answer explanation

Producers need inputs, much like ingredients for cookies, to make the ESM glucose they need to thrive. First you need to add ​ (a)   to the leaves. Then the leaf will let in the ​ (b)   through the stomata. Finally the roots will draw up ​ (c)   and they meet in the chloroplast as input. The product is delicious ​ (d)   and oxygen.

• the sun's energy

• CO2

• H2O

• glucose

• protein

• ATP energy

• mitochondria

• amino acids

Answer explanation

Are you having trouble remembering how chloroplasts perform photosynthesis to turn carbon in the air from abiotic matter (not living), into biotic matter (living) called glucose!

Abiotic matter is a scientific term for things in our ecosystem that are not living - they do not reproduce. The​ (a)   that shines , the​ (b)   we breath, the ​ (c)   we drink, and the ​ (d)   we climb are all examples of abiotic matter.

• sun

• air

• water

• rocks

Answer explanation

Take a look at the chart. To be abiotic, they cannot reproduce. These are some examples of the abiotic matter in our ecosystem.

Which type organisms can all perform photosynthesis?

• Decomposers - fungi, mushrooms, ants, worms, bacteria

• Producers - plants, algae, trees

• Consumers - deer, cats, snakes.

Answer explanation

While there are a few consumers that have adapted to use photosynthesis for food, the correct response is producers. Producers have the chloroplast organelle. This is where the suns energy combines with water, and CO2 to create glucose and oxygen.

​ (a)   are critical for every ecosystem. _​ (b)   are a life line for producers. You see, ​ (c)   break down ​ (d)   matter and release the ​ (e)   back into the air, so producers can perform photosynthesis.

• Producers

• Decomposers

• decomposers

• dead

• carbon

Answer explanation

All living things need ESM.

Decomposers eat the dead matter and this helps you out!

Dead matter like, dead plants, fruit, vegetables, trees, etc.

When they eat the dead matter and clean up the waste in an ecosystem, they release CARBON back into the air for the producers to use for photosynthesis.

In the cells of our bodies you will find many ​ (a)   . This important organelle is where cellular respiration happens. ​ (b)   and ​ (c)   are inputs and they create ATP energy, ​ (d)   and ​ (e)  

• mitochondria

• Oxygen

• glucose

• H2O

• CO2 - carbon dioxide.

Answer explanation

Fun Fact! We ALL do cellular respiration for energy. It also give us H2O and CO2.
