Energy flow Flashcards
What are animals that feed on other a animals called
Carnivores
What are animals that feed on plants called
Herbivores
What is a carnivore that kills the animal they eat called
Predators
What is the animal that a predator kills and eat called
Prey
What is an animal that eats plants and animal called
Omnivores
What is the producer of a food chain called
Green plants as they produce their own food through the process of photosynthesis
What is the source of energy for a food chain
The sun
What are animals in a food chain
The consumers
What is a herbivore in a food chain
The primary consumer
What is a carnivore in a food chain called
The secondary consumer
What is the larger carnivore in the food chain that eats the secondary consumer called
The tertiary consumer
What do we call a food chains linked together
A food web
Chemicals get more concentrated as they pass through the food web what is this called
Bioaccumulation
As you moved along the food chain what happens to the level of pesticide
The level of pesticide increases
What do the arrows in the food chain represent
The flow of energy
What is the difference between a food chain and a food web
A food chain shows the transfer of energy between organisms symbolised by arrows food chains are interlinked to form food webs
How do organisms lose energy
When an organism respires some energy is lost as heat
Energy lost to maintain and repair cells
Lost in movement and to maintain body temperature
Energy lost in waste as they cannot digest every part of food they eat
When carnivores eat an animal what don’t they usually eat
Bones
When herbivores eat plants what don’t they usually eat
Roots and shoots
What type of energy is not wasted in the food chain
Energy that organisms use for growth as it is more for the predator to eat
How much stages does a food chain usually go on for
Four or five stages
What happens to the animals as you go down the food chain
The populations get smaller as there isn’t as much energy to digest
What does the height and width represent in the ecological pyramid
The width of each block is the proportional to the total number/mass of the organisms in each stage
The height means nothing
What is a ecological pyramid
They show the population size of each organism in each stage of a food web
What are the two pyramids called
The pyramid of number which record the numbers in each stage
The pyramid of biomass which record the total mass of the population at each stage of the food chain
