Got Biotics and Abiotics?
Organisms are not separated from their environment
Do organisms live in isolation?
The interactions between biotic factors and abiotic factors
What is ecology?
Diagrams that represent feeding relationships of different species
What are Food Chains and Food Webs?
Each step of the food chain in the energy pyramid
What is trophic level?
These things absorb carbon dioxide and need water to survive
What are plants?
A symbiotic relationship in which one organism benefits and the other is harmed. A leech attaching to a host's body and sucking the host's blood is an example.
What is Parasitism?
Anything in the environment that causes a reaction or response.
What is a stimulus?
They can balance the structure of the community.
What is a benefit of predator-prey relationships?
Parts of the environment that are not living
What is abiotic?
A group of organisms belonging to the same species, that live in the same area, and interact with one another
What is a population?
Organisms that cannot make their own food and must get energy from other living organisms
What are consumers?
Autotrophs
What are producers?
One must eat, to get energy
How to survive?
A symbiotic relationship in which two different organisms help each other and both benefit equally. Bees pollinating flowers as they sip the flowers' nectar is an example.
What is Mutualism?
The maximum population size that can be supported in a particular area without destroying the habitat
What is the Carrying Capacity?
Size of each population
What is in flux (continuous change) because of predator-prey relationships?
Parts of the environment that are living
What is biotic?
All of the populations of different species that live in the same area and interact with one another
What is a community?
Organisms that get nutrients and energy by breaking down the remains of dead organisms or animal waste
What are decomposers?
A scientific name for organisms that cannot produce their own food
What are heterotrophs?
All organisms in the reading
What is have the ability to grow and reproduce?
A symbiotic relationship in which one organism benefits and the other neither benefits nor is harmed. Barnacles attached to a whale is an example.
What is Commensalism?
This determines the carrying capacity of a population
What are Limiting Factors?
The struggle between two or more organisms or two or more kinds of organisms for resources in a short supply.
What is competition?
Includes the living organisms in an area and the non-living aspects of their environments and their interactions
What is an ecosysytem?
The role an organism plays in its ecosystem
What is a niche?
A single pathway by which energy and matter flow through an ecosystem
What is a food chain?
There is a loss of energy
What happens every time energy is transferred from one organism to another?
Warthogs chased by these cats
What are cheetahs?
A clownfish and an anemone
What is Mutualism?
This can have dramatic consequences on a population
What is food?
Competition between members of the same species, aka Intraspecific or different species, aka Interspecific.
What are the two ways that competition can happen?
Rocks, water, air
What are examples of abiotic factors in an environment?
The highest level of ecological organization, it is part of the Earth
What is the Biosphere?
Multiple pathways through which energy and matter flow through an ecosysytem
What is a food web?
10% of total energy
What is the amount of energy that is absorbed into an organism at the next trophic level?
This animal has antlers and spots in the picture
What is a deer?
A Tick and a Dog
What is Parasitism?
Use of pesticides such as DDT, use of herbicides and habitat destruction.
What are Human activities that can limit the growth of populations?
Materials from the environment that living things use to live and grow. Food, water, and shelter are examples.
What is a resource?
