The Basics
This includes all of the living things that can be found within a given area.
What is an ecosystem?
These are biotic elements that makes their own food.
What are producers?
This is described as a community of plants and animals that have common characteristics for the environment they exist in.
What is a biome?
Energy transfers always begin with this abiotic element.
What is the sun?
These factors control or limit the number and health of biotic elements in an ecosystem.
This is the percent of energy that is passed on through the the trophic levels of a food chain.
What is 10%?
Living elements in an ecosystem are called_________
What are biotic elements?
These are biotic elements that reply on feeding interactions to supply their food needs.
WHat are consumers?
This biome receives a lot of rain each year. This amount of rain allows the plant life to grow and be dense. Trees in this ecosystem grow very tall, as they compete for sunlight. Animals make their home in these trees and under the trees leaves.
What is a rainforest?
The levels of energy flow are called this.
What are trophic levels?
True or false; Limiting factors of an ecosystem can be biotic or abiotic.
What is true?
Most energy is lost through __________ during energy transfers.
What is te head?
Non-living elements are called __________.
What are abiotic elements?
These are the 3 mains types of consumers.
What are herbivore, omnivore, and carnivore?
This biome is the largest in the world.
What is marine biome?
This is a complex network of showing how energy is transferred in feeding interactions in an ecosystem.
What is a food web?
Scientists use the term ___________ to describe the introduction of these introduced species into a native ecosystem. We sometimes refer to these species as ________________.
What are bioinvasion and invasive species?
An animal that is hunted for food is called the ______, while the animal that hunts and consumes the prey is called the ___________.
WHat are prey and preditor?
These are the 4 basic needs if biotic elements.
What are water, food, air and shelter?
These are the 3 types of special consumers.
What are decomposers, scavengers, and detritivores?
This biome can be found in warmer parts of the world – such as in Africa. These ecosystems have wide, treeless grounds that are often the home of grazing animals. These animals feed off of the grass, rather than trees. Temperatures here vary from summer to winter, and the amount of rainfall is less than other ecosystems.
What are Grasslands?
These are the 4 levels of the trophic energy pyramid, starting at the bottom.
What are producers, primary consumers, secondary consumers, and tertiary?
This is a series of steps in a cycle that allow abiotic elements to be used over and over again. These abiotic elements are absorbed and used by producers to form organic matter. Consumers then absorb the organic matter through feeding interactions and use it for growth. As they grow, they produce organic waste. Decomposers then break down the organic waste from living or dead organisms into abiotic elements that producers use again.
What is cycling matter?
This special consumer feeds on the remains of already dead animals, this one eats dead organisms, this one feeds on the remains of already dead animals, while this one feeds on waste.
What are scavengers, decomposers, and scavengers?
Water in an example of a _____________ element where a tree is an example of a ___________ element.
What are abiotic and biotic?
These are the 3 main roles of producers.
What are produce oxygen, supply energy and provide shelter?
This is the biome that we live in.
What is temperate biome?
If a plant (producer) gives 35 000 Kcal energy to a rabbit (primary consumer), and the rabbit gives 3500 Kcal of energy to the fox (secondary consumer), then the fox will give ____________ Kcal of energy to the coyote.
What is 350?
These factors are affected by the number of organisms in an ecosystem. eg the amount of food available for each organism is connected to the amount of organisms in the ecosystem. vs limiting factors that are not connected to the amount of organisms in an ecosystem. eg. The amount of rain does an ecosystems gets is not based on the amount of organisms that live there.
What is dependent limiting factors and independent limiting factors?
This is the different between native species and introduced species in an ecosystem?
What are native species are naturally found in the ecosystem, whereas introduced species never lived in the ecosystem before and were brought there?
