| Question | Answer |
|---|---|
| The energy in most ecosystems comes from | the sun |
| True or False: Most organisms can survive if they are taken away from their habitat. | false |
| The community of a pond is made up of many different what? | populations |
| When organisms can adapt to their physical surroundings or to each other this is called: | evolution |
| An organism that rejects a chemical because it has a gene that protects it from the chemical has developed this | resistance |
| The process of two species changing genetically in response to long-term interactions with each other is called? | coevolution |
| Individuals with a trait that is “naturally selected” must have this occur for evolution to occur in a population? | reproduction |
| Most scientists classify organisms into how many kingdoms? | six |
| Converts nitrogen in the air into a form plants can use | bacteria |
| What is an algae that uses energy from the sun to make food? | seaweed, phytoplankton or giant kelp |
| Cone bearing plants with seeds not enclosed in fruits | gymnosperms |
| Land animals depend on angiosperms for this | food |
| Air and temperature in an ecosystem are this type of factor in an ecosystem | abiotic factors |
| Humans have inadvertently promoted the evolution of insects by trying to control pests with chemicals which has created this in the insects | resistance |
| Members of the same species living in the same place at the same time | population |
| Bacteria and fungi are important to the environment because they are critical in doing this? | breaking down dead organisms |
| Roots, insects and leaves are this type of factor in an ecosystem | biotic |
| Single-celled organisms with cell walls but no nuclei | bacteria |
| Which two kingdoms contain organisms that can use energy from the sun to make food? | protists and plants |
| Many angiosperms depend on this to disperse their seeds. | animals to carry pollen |
| Characteristics is usually shared by bacteria, fungi, and plants? | usually have cell walls |
| A conifer is considered this type of plant | gymnosperm |
| If an insect can no longer be killed by a particular insecticide, it has developed | resistance |
| Most bacteria, including the kinds that cause disease and those found in garden soil, belong to this kingdom | eubacteria |
| The initial source of food in most ocean and freshwater ecosystems | phytoplankton or algae protists |
| The initial source of food in most land ecosystems | plants –specifically angiosperms |
| Pine trees and other conifers are classified as this because they are woody plants, the seeds of which are not enclosed in fruits | gymnosperms |
| The living and once living parts of an ecosystem, including all the plants and animals, are this type of factor in the ecosystem | biotic |
| The nonliving parts of an ecosystem, such as rocks, light, air, and temperature, are this type of factor in the ecosystem | abiotic |
| Raccoons in Tennessee and raccoons in Illinois are members of the same | species |
| Raccoons in a forest in Wisconsin would be described as this level of organization | population |
| The place where an organism lives and that has the resources the organism needs | habitat |
| Darwin proposed that this is the mechanism for the change in the genetic characteristics of a population from one generation to the next, aka evoluation. | natural selection |
| An inherited trait that increases an organism’s chance of survival and reproduction in a certain environment | adaptation |
| A collie is a breed of dog that exists because of this type of selection. | artificial |
| Bacteria are members of these 2 kingdoms. | archaebacteria, eubacteria |
| Algae are a type of organism in this kingdom | Protista |
| Unlike other organisms these do not have cell nuclei | bacteria |
| A mushroom top above ground is this part of a structure of a fungus. | reproductive |
| Yeasts that make bread rise belong to the this kingdom. | fungi |
| The one-celled organisms that cause malaria belong to this kingdom. | protista |
| Many-celled organisms that have cell walls and make their own food | plants |
| The leaves and roots of trees and other plants are connected by this type of tissue, which is a system of tubes that carry water and food. | vascular |
| Plant that produces seeds that are not in fruit | gymnosperm |
| Plant that produce flowers and bear seeds in fruit. | angiosperm |
| Animals that lack backbones | invertebrates |
| Animals that have backbones | vertabrates |
| Athlete’s foot is a disease caused by this? | fungi |
