• Reduced nutrient uptake

Take a look at this dandelion. The yellow flower on the right is _______ pollinated and the seeds on the left are transported by ___________.

• wind; water

• insect; wind

• insect; birds

• animals; water

Which of the following is NOT a long-term consequence of drought on plants?

Cattle, Bison and Elephants all travel in herds. What is the main purpose of these animals practicing this behavior? Select all that apply

• To protect young from predators

• To decrease reproduction

• Safety in numbers

• Increase odds of successfully finding food and water by traveling in numbers

Jimmy and Karen conducted an experiment comparing tomato plant growth and the amount of fertilizer applied to each plant. The plants were kept in the same location, received the same amount of water, and the pots contained the same type of soil.

Jimmy and Karen concluded that the more fertilizer they applied, the better the plant growth. What comment would you make about their conclusion?

• The conclusion matched the data.

• They should omit the data for Plant 5 and keep their original conclusion.

• A better conclusion would be that fertilizer amount had no effect on plant growth.

• The highest fertilizer rate resulted in a dead plant; they should change their conclusion.

What type of animal usually practices herding behaviors? Select all that apply

• Predator

• Prey

• Herbivore

• Carnivore

How does overbreeding impact animal populations?

• Increased genetic diversity

• Decreased competition for resources

• Reduced risk of disease outbreaks

• Limited availability of food and space

Identify one plant seed structure that plays a role in successful reproduction.

• Fast germination

• Being colorful

• Hard shells

Some plants emit sweet smells to attract pollinators, others such as the corpse plant emit a foul odor that smells like rotting material. What is the greatest negative impact of emitting this type of odor?

• It only attracts a specific type of pollinator that limits its chances of successful reproduction and making it vulnerable to extinction

• The plant blooms very rarely and only for a short period of time.

• The odor deters the majority of organisms that are pollinators

What is the purpose of odor in plants?

• To attract pollinators

• To scare away predators

• To provide shade

• To store nutrients
