Unit 1: Practice Exam and Review 1.1: Organization and Characteristics of Life
1. Which of the following is the correct order for the organization of life? a. Ecosystems → communities → populations → organisms → organs → organ systems → tissues → cellsb. Cells → tissues → organs → organisms → organ systems → populations → communities → ecosystemsc. Ecosystems → communities → populations → organisms → organs → organ systems → cells → tissuesd. Cells → tissues → organs → organ systems → organisms → populations → communities → ecosystems

4. Which of the following is an abiotic component of a desert in California?a. cactib. windmillsc. dead scorpiond. horned lizard
5. Every species has a role that it plays in nature. That role is defined by a combination of the organism's behaviors, habitat, and interaction with other species. For example, a garden spider is a predator that hunts for prey among plants, while an oak tree grows to dominate a forest canopy, turning sunlight into food. The oak tree provides the food and protection in the canopy. This is its _____________.
a. speciesb. habitatc. ecosystem d. niche
6. Last year you caught the flu during flu season. Flu season is coming up again and your doctor recommends you get the new flu shot. Why does your doctor recommend this?
a. Because the flu is strong. b. Because the flu is a virus made up of DNA. c. Because the flu can make you sick.d. Because the flu virus has adapted and changed from the strain last year.
7. What is commonly known as the smallest abiotic unit? ATOM8. What is commonly known as the smallest biotic unit? CELL
9. Compare and contrast a niche and a habitat. A habitat is the home or ecosystem that an organism lives in whereas a niche is all of the ways an organism uses

1.3 Ecological Relationships
1. The chinstrap penguin is a species of penguin which inhabits a variety of islands and shores in the Southern Pacific and the Antarctic Ocean. The shore can be a dangerous place with the waves crushing along the sides of the island. The penguins must face the harsh waters when they dive in, in search of fish. The waves are an example of what kind of environmental factor?
a. Bioticb. Abioticc. Symbiosisd. Competition
2. Everything on the islands has to compete for space and food. The male Pygmy three-toed sloth searches for a mate by responding to her calls and swimming towards her. Other male Pygmy three-toed sloths also hear the call, and will compete to be the first to reach the potential mate. This is an example of:
a. Mutualismb. Commensalismc. Intraspecific Competitiond. Interspecific Competition
3. The iguanas help other animals on the island to survive by bringing nutrients from the sea to the land.

This is an example of what kind of relationship?
a. Mutualismb. Commensalismc. Invasive Speciesd. Parasitism
4. The yellow crazy ants on Christmas Island were brought on ships and invaded the island. They are not native to Christmas Island. They attack crabs, squirting acid into their eyes and mouths as they try to defend the territory that they both compete for. Which of the following terms best describes this example?
a. Mutualismb. Commensalismc. Interspecific competition
d. Intraspecific competition
5. Fairy terns live on islands and use the trees on the island to nest with their eggs. Rather than constructing a nest, they use trees that have a cavity or gap in which they can put their egg in. The fairy terns benefit from the tree, but the trees are not affected from the birds. Which of the following terms best describes this example?
a. Mutualismb. Commensalismc. Invasive Speciesd. Parasitism
6. Mistletoe is a plant that attaches itself to a tree or shrub by a structure called a haustorium, which it uses to extract water and nutrients from the tree or shrub. Which of the following best describes this example?
