Work on all missing assignments and Test Remediation Topics

Chapter 4 Vocabulary Ecosystem- a community of organisms and their abiotic environment. Community- a group of various species that live in the same habitat and interact with each other. Biotic factor- an environmental factor that is associated with or results from the activities of living organisms. Habitat- the place where an organism usually lives. Abiotic factor- the nonliving part of the environment, including water, rocks, light, and temperature. Natural selection- the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution. Organism- a living thing: anything that can carry out life processes independently. Species- a group of organisms that are closely related and can mate to produce fertile offspring: also the level of classification below genus. Evolution- a heritable change in the characteristics within a population from one generation to the next: the development of new types of organisms from preexisting types of organisms over time. Population-a group of organisms of the same species that live in a specific geographical area and interbreed.

Chapter 4 Vocabulary continued Adaptation-an anatomical, physiological, or behavioral change that improves a population’s ability to survive. Fungus- an organism whose cells have nuclei (eukaryotic), rigid cell walls, and no chlorophyll and that belong to the kingdom Fungi. Protist- an organism that is typically single celled, eukaryotic and found in water. Artificial selection- the selective breeding of organisms (by humans) for specific desirable characteristics. Gymnosperm- a woody vascular seed plant, whose seeds are not enclosed by an ovary or fruit. Resistance- the ability of an organism to tolerate a chemical or disease-causing agent. Angiosperm- a flowering plant that produces seeds within a fruit. Archaebacteria- a kingdom made up of prokaryotes, most of which are known to live in extreme environments. Invertebrate- an animal that does not have a backbone. Eubacteria- a kingdom made up of all prokaryotes, true bacteria with a cell wall of peptidoglycan. Vertebrate- an animal that has a backbone: includes mammals, birds, reptiles, amphibians, and fish.

Ecosystems Where does the energy in an ecosystem come from? What are some examples of an ecosystem? Which of the following organisms are likely to belong to the same species? Animals in a forest Bacteria in your body Organisms in Lake Lanier People at West Hall

Ecosystems What is a population? What are some biotic factors? What are some abiotic factors? What type of factor would rocks and air be considered?

Habitats/Types of factors What is a habitat? What are the nonliving parts of an ecosystem? What are the living and once living parts of an ecosystem?

Communities Can most organisms survive if they are taken away from their habitat? What would you find in a lake community?

Adaptations What can organisms adapt to? Why are some organisms more likely to survive? In order for evolution to occur in a population, what must an individual do if it has the trait that is naturally selected for?

Evolution How does an organism become resistant to a chemical? What is coevolution? How have Humans inadvertently (accidentally) promoted the evolution of insects that are resistant to insecticides?

Evolution If an insect can no longer be killed by a particular insecticide, it has developed a(n) ____________________ to the chemical. What did Darwin propose was the mechanism for evolution? What is the change in the genetic characteristics of a population from one generation to the next?

Evolution What is an inherited trait that increases an organism’s chance of survival and reproduction in a certain environment? What type of selection produced a collie as a breed of dog that exists?

Classification What categories or groups are organisms classified into? What do bacteria and fungi both have in common? What is a single-celled organism with a cell wall but no nuclei?

Organisms Which animal is successful because it moves quickly, reproduces rapidly, and has a waterproof external skeleton? What converts nitrogen in the air into a form plants can use? List some algae that use energy from the sun to make food?

Kingdoms Why are angiosperms useful for humans? What do angiosperms need animals for? In what kingdom would a gymnosperm be found in?

Diversity of Life What characteristic is usually shared by bacteria, fungi, and plants? Which two kingdoms contain organisms that can use energy from the sun to make food? What types of organisms do not have a nucleus?

Organisms What are organisms that have a backbone called? What are organisms that do not have a backbone called? What causes athlete’s foot? What kingdom are yeast part of?

Kingdoms What are many-celled organisms that have cell walls and make their own food called? What kingdom are algae part of? What kingdoms are bacteria part of?

More Kingdoms What are pine trees and other conifers are classified as since they are woody plants and their seeds are not enclosed in fruits? What kingdom are most bacteria, including the kinds that cause disease and those found in garden soil, classified in? What is the initial source of food in most ocean and freshwater ecosystems?
