Interdependency
All of the living and non-living things,and all of their interactions in an area
Ecosystem
A path of energy transfer from one organism to another
Food Chain
The space, conditions, and all the living and nonliving things around an organism
Environment
The continuous exchange of gasses between living organisms and the environment
Carbon Dioxide - Oxygen Cycle
Some beetles break down the remains of dead animals. Some mushrooms break down the remains of dead trees. How do these actions most benefit plants?
A. By returning nutrients to the soil
B. By releasing oxygen into the air
C. By making space for new animals
D. By decreasing the population of herbivores
A. By returning nutrients to the soil
Possessing the capacity for metabolism, growth, reproduction, and response to stimuli
Living
An interconnected set of food chains
Food Web
The action of one object having a lasting effect or influence on a situation, person, or environment
Impact
The waste product produced by plants during photosynthesis that animals use for respiration
Oxygen
In a food chain, energy does NOT flow directly from:
A. producer to decomposer
B. producer to consumer
C. consumer to decomposer
D. consumer to producer
D. consumer to producer
Something that does not grow, reproduce, or use energy
Non Living
An organism that hunts and feeds on another organism.
Predator
Maximum population size that can be sustained by a given environment.
Carrying Capacity
A gas produced by cells during respiration; used in photosynthesis to produce sugars
Carbon Dioxide
Wild hogs eat many different kinds of foods, including plants, fungi, and insects. Besides being very destructive to the habitats of other animals, how do wild hogs most likely harm other animals.
A. By competing with other animals for food
B. By moving slower than most other animals
C. By causing other animals to reproduce more
D. By eating foods that no other animals eat
A. By competing with other animals for food
Any individual living thing that can function on its own
Organism
An animal that is hunted as food
Prey
All of the interacting members of the same species in an area.
Population
A process by which animals use oxygen and food to make energy and carbon dioxide
Respiration
Animals and plants use substances that cycle through the environment. Which substance is needed by plants to survive and is released into the environment by animals?
A. Oxygen
B. Sugar
C. Salt
D. Carbon Dioxide
D. Carbon Dioxide
The evolutionary process where a species becomes better suited to its environment
Adaptation
Organisms that break down dead material
Decomposers
The condition where the number of living entities (human, animal, or otherwise) exceeds the carrying capacity of their environment
Overpopulation
The process where plants use sunlight, water, and carbon dioxide to produce sugar and release oxygen
Photosynthesis
What would most likely happen to the carbon dioxide-oxygen cycle if Earth's large forests were all cut down?
A. There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food
B. The remaining plants would stop producing carbon dioxide, and animals would use less oxygen
C. The remaining plants would produce more oxygen, and animals would produce less carbon dioxide
D. There would be more oxygen in the atmosphere because few plants would be using it to produce their own food
A. There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food
