Intro To Ecology
What is the difference between an aboitic factor and a biotic factor?
Biotic--> an interaction between organisms in an area (alive)
Abiotic--> nonliving part of an environment
Organisms get energy by food
*Plants get energy from the sun (photosynthesis)
What is a niche?
The role the population plays in the ecosystem, such as how it gets food and interacts with other populations
What is a consumer?
A consumer is an organism that eats other organisms
What is Cellular Respiration?
The process of breaking down food to produce ATP using oxygen
What is Ecology?
Ecology is the study of how organisms interact with one another and with the enviroment
How is energy transferred among organisms?
Energy s transferred among organisms by food webs or chains. For example, if a rabbit eats grass then it gets the energy of the grass.
What is a habitat?
The place where an organism usually lives and is part of an organisms niche
What is an omnivore?
An omnivore is an organism that eats both meat and herbs
What are the reactants of photosynthesis?
Sun Light, Water, and Carbon
What are the levels of organization in the environment?
1. Population (A group of individuals that are the same species)
2.Species (All organisms that are closely related)
3.Community (All populations of different species that are biotic factors)
How do food webs show (energy) connections?
Food webs show energy conditions by using arrows. If you were to map out a food web or food chain the energy being transferred through organisms would be represented by arrows
What is a producer?
A producer is a plant that uses energy from the sun to make food
What is a carnivore?
A carnivore is an organism that only eats meat
What are the Products of Cellular Respiration?
Water and Carbon
What is a biome?
A biome is a large region characterized by climate and communities of species
What is the difference between a food web and a food chain?
A food web has multiple routes to the person at the top of the food web while a food chain has only one route
What is photosynthesis?
Photosynthesis is using sunlight to make food
What is a herbivore?
A herbivore is an animal that eats plants and herbs
What are the reactants of Cellular Respiration?
Sugar and Oxygen
What characteristics define a biome?
Climate Conditions and Communities of living things
How much energy is lost at the levels of a food chain or food web?
90% of energy is lost
What is a decomposer and what are examples of it?
A decomposer is an organism that gets energy and nutrients by breaking down the remains of other organisms
Fungi, Mushrooms, Bacteria
What is a consumer also called?
A consumer is also called a hetertroph
What is ATP?
ATP powers many reactions making an organism to survive. It stands for adenosine triphosphate
