abiotic/biotic
All ecosystems are made up of _______ and _____ components.
biotic/plant/animals
______ factors are living things, such as ______, or _______.
aboitic/moisture/wind/temperature
______ factors are nonliving things, such as ______, ______, or ________.
amount of species in one biome
What is biodiversity?
keystone species
What is the term for an organism that has an unusually large effect on its ecosystem?
create beaver ponds, creates habitats for animals
Why is a beaver an example of a keystone species?
the living parts of an ecosystem; plants, animals, fungi, and bacteria
What is a biotic factor?
the nonliving parts of an ecosystem; wind moisture, temperature,sunlight, and soil
What is an abiotic factor?
variety of living things in an ecosystem
What is biodiversity?
the more the habitat is destroyed the less organisms there will be in an ecosystem
Why might it be important to preserve areas with high biodiversity?
Producers/nonliving
____ are organisms that get their energy from _____ resources, meaning they make their own food.
Autotrophs
Organisms that make their own food are called _____.
Consumers/eating
_____ are organisms that get their energy by _____ other organisms.
Heterotrophs
Organisms that get their energy from other organisms are called _____.
They create the base of the food chain/food web
Why are producers so important to an ecosystem?
sun provides nutrients for producers, consumers eat producers
Why is the sun important to both producers and consumers?
producer produces its own food, consumers rely on producers or other consumers for food
What is the difference between a producer and a consumer?
producers are the base of all food webs and food chains
Why do all ecosystems depend on producers?
they depend on producers and producers depend on the sun
How are consumers dependent on the Sun?
photosynthesis is changing light to nutrients, chemosynthesis changes chemicals into carbohydrates
What is the difference between photosynthesis and chemosynthesis?
organism/organisms/ecosystem
A food chain follows the connection between one _____ and a single chain of _____ within an _____.
herbivore
I eat only plants. I am a(n) _____.
carnivore
I eat only other animals. I am a(n) _____.
omnivore
I eat both plants and animals. I am a(n)_____.
detritivore
I eat dead organic matter. I am a(n) _____.
decomposer
I break down organic matter into simpler compounds. I am a(n) _____.
primary consumer
I am the first consumer above the producer level. I am a(n)_____.
secondary consumer
I am a carnivore that eats herbivores. I am a(n) _____.
tertiary consumer
I am a carnivore that eats other carnivores. I am a(n) _____.
trophic levels
The levels of nourishment in a food chain are called _____.
food web shows what organisms eat, food chain shows trophic levels
How is a food chain different from a food web?
it decreases
What happens to energy at each link in a food web?
producers
What type of organism provides the base of a food web?
specialist eats specific organisms, generalist eats many different organisms
Use your knowledge of the words special and general to explain the diets of specialist and a generalist.
herbivore, carnivore, omnivore, and detritivore
What are the four main types of consumers?
specialist eats specific organisms, generalist eats many different organisms
What is the difference between a specialist and a generalist?
producer, primary consumer, secondary consumer, and tertiary consumer
What are the trophic levels in a food chain?
pyramid designed to show the distribution of energy between tropic levels
What is an energy pyramid?
a measure of the total dry mass of organisms in an ecosystem
What is a biomass?
energy it lost at every level
Describe the flow of energy from one trophic level to another.
biomass pyramid compares the biomass of different tropic levels in an ecosystem/pyramid of numbers is the number of each organism at each trophic level
What is the difference between a biomass pyramid and pyramid of numbers?
