Which of the following organisms is the primary consumer in this food web?

[ "kelp", "sea otter", "phytoplankton", "zooplankton" ]

D

Primary consumers eat producers. So, in a food web, primary consumers have arrows pointing to them from producers. The sea otter has an arrow pointing to it from the sea urchin. The sea urchin is not a producer. So, the sea otter is not a primary consumer. The sea urchin has an arrow pointing to it from the kelp. The kelp is a producer, so the sea urchin is a primary consumer. The phytoplankton does not have any arrows pointing to it. So, the phytoplankton is not a primary consumer. The zooplankton has an arrow pointing to it from the phytoplankton. The phytoplankton is a producer, so the zooplankton is a primary consumer. The kelp does not have any arrows pointing to it. So, the kelp is not a primary consumer.

What do these two changes have in common? mixing sand and water cutting your fingernails

[ "Both are caused by cooling.", "Both are chemical changes.", "Both are only physical changes.", "Both are caused by heating." ]

C

Step 1: Think about each change. Mixing sand and water is a physical change. Adding water makes the sand wet. But both the sand and water are still made of the same type of matter as before. Cutting your fingernails is a physical change. Your fingernails are shorter after you cut them. But the pieces are still made of the same type of matter as the uncut fingernails. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? rust forming on a metal gate photosynthesis

[ "Both are only physical changes.", "Both are caused by cooling.", "Both are chemical changes.", "Both are caused by heating." ]

C

Step 1: Think about each change. Rust forming on a metal gate is a chemical change. As the gate rusts, the metal turns into a different type of matter called rust. Rust is reddish-brown and falls apart easily. Photosynthesis is a chemical change. Plants make sugar using carbon dioxide, water, and energy from sunlight. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

C

Use the arrows to follow how matter moves through this food web. For each answer choice, try to find a path of arrows to the sea cucumber. No arrows point from the bat star to any other organisms. So, in this food web, matter does not move from the bat star to the sea cucumber. The only arrow pointing from the black rockfish leads to the kelp bass. The only arrow pointing from the kelp bass leads to the bat star. No arrows point from the bat star to any other organisms. So, in this food web, matter does not move from the black rockfish to the sea cucumber.There is one path matter can take from the orca to the sea cucumber: orca->sea cucumber. kelp bass. The only arrow pointing from the kelp bass leads to the bat star. No arrows point from the bat star to any other organisms. So, in this food web, matter does not move from the kelp bass to the sea cucumber..
