The ABIOTIC factor limiting the population size in this ecosystem.

What is LIMITED SPACE?

100

In the image above, this is the primary consumer.


What is the grasshopper?

100

This is when the removal of a keystone species causes widespread effects on many other species in the ecosystem.

What is a trophic cascade?

100

When an initial stimulus (something happens to a system) gets amplified in order to complete a process, like childbirth, it is called this type of feedback.

What is positive feedback?

100

Based on the data above, this suspect (1, 2, or 3) was most likely at the crime scene.

Who is suspect 2?

200

The carrying capacity of the rabbit population shown in this graph.

What is 6,000?

200

In the image above, this species is the secondary consumer.

What is the sea otter?

200

When you remove this species from an environment, it causes a trophic cascade.  The ecosystem loses biodiversity and becomes unbalanced.

What is a keystone species?

200

When an initial stimulus is reversed in order to bring the body/system back to homeostasis, like when a person sweats in order to bring their body temperature back to normal, it is called this type of feedback.

What is negative feedback?

200

The genes that an organism has for a particular trait (ex. Bb) is called their genotype, whereas the physical appearance of those traits (ex. brown fur) is known as their...

What is phenotype?

300

Based on the evidence in these graphs, the shark preys upon this species.

What is the Ray?

300

In the image above, this species is the tertiary consumer.

What is the seal?

300

Urchins eat kelp, so when urchin populations go up, kelp populations go down.  Urchins have this kind of effect on kelp.

What is a direct (negative) effect?

300

Cells contain many of these, which are specialized to perform different jobs/functions in the cell.  The endoplasmic reticulum is an example of one.

What is an organelle?

300

A steak with butter contains these TWO macromolecules.

What are lipids/fats and protein?

400

An outside or environmental influence that impacts population phenotypes.  (Ex: Poachers hunt elephants for their tusks, so tuskless elephants became more common in elephant populations.  The poachers were an example of this.)

What is a selective pressure?

400

Approximately this much energy gets passed from one level in an energy pyramid to the level above it.

What is 10%?

400

If otters are taken out of the ecosystem the kelp population will decrease, even though otters don't eat kelp.  Otters have this type of effect on kelp.

What is an indirect (negative) effect?

400

In a cell, DNA is contained in the nucleus.  The DNA provides instructions for building proteins.  THESE small organelles are responsible for building proteins.

What are ribosomes?

400

Maintaining balance in an ecosystem or within an organism is known as this.

What is homeostasis?

500

Ocean ecosystems can suffer when the pH of the ocean is reduced, causing the ocean to become more acidic.  This is usually a result of increased WHAT in the atmosphere?

What is carbon dioxide?

500

These organisms break down dead and decaying matter from all trophic levels.

What are decomposers?

500

Of ecosystem A or B, the one with LESS biodiversity.

What is ecosystem B?

500

When a cell is placed in a solution with A LOT of solute, THIS SUBSTANCE will usually leave the cell, making the cell smaller.

What is water?

500

In the carbon cycle, photosynthesis removes carbon from the atmosphere.  This process adds it to the atmosphere.

What is

Respiration, combustion, decay, or decomposition?
