The arrows in a food chain or web represents what?

• They point to the organism that is being eaten.

• It shows how sunlight flows within an ecosystem.

• They show what direction the energy is flowing between organisms. 

• They represent how water is transferred within a habitat.

In a typical energy pyramid, the ​ (a)   have the most energy and the ​ (b)   have the least energy because only​ (c)   of an organism's energy passes on to the next level of the energy pyramid so as you progress up the energy pyramid the energy​ (d)   from level to level

• Primary consumers

• Secondary consumers

• Primary producers

• Tertiary consumers

• 10 percent

• decreases

• 90 percent

• Secondary Consumer

• 0.1

• Producers

• 1

• Tertiary Consumer

• 10

• Primary Consumer
