- What trophic level are herbivores in
- 2nd
- Are chemosynthesis autotrophs
- yes
- mechanical energy for
- movement
- energy passes through an ecosystem by
- respiration
- scavengers eat
- food thats already dead
- 2nd Trophic Level
- Consumer Herbivore
- How do autotrophs get carbon from
- photosynthesis
- Organisms need nitrogen to make
- proteins
- What trophic levels are secondary carnivores in
- 4th
- Trophic Level
- the specific feeding level in a food chain
- Examples of decomposers are
- fungi and bacteria
- carbon passes through trophic level as .. which is
- tissue eaten
- Explain lettuce - caterpillar - bird - cat include trophic levels and describe
- Lettuce producer 1, caterpillar consumer herbivore 2, bird primary carnivore 3, cat secondary carnivore 4
- Organisms need carbon to make
- organic compounds
- decomposers release ______ as they feed on ____ _____ and _______ ______
- energy dead plant animal matter
- Food Chain
- a chain of organisms through which energy flows
- how is carbon released back into the atmosphere by ... by ...
- respiration plant, animals, decomposers
- Difference between decomposers and detritivores
- Decomposer break down and detritivores consume
- Primary Carnivores obtain food by
- eating herbivores
- two main types of energy flows
- grazing and organic detritus relationship
- Energy enters as light and leaves as
- heat
- is energy recycled
- no
- Is nutrient a cycle or flow
- cycle
- energy flow is a
- one way movement of energy in a ecosystem
- main reservoir of carbon is (oceans, rock, soil)
- limestone
- energy is used by plants for
- growth
- Secondary Carnivores obtain food by
- eating primary carnivores
- Energy pyramids show
- proportion of energy stored in each trophic level
- Food Web
- network of many food chains linked together in a community
- Chemosynthesis
- using chemical reactions to make food
- Why do organisms need organic compounds
- carbon atom is a key compound in carbohydrates, proteins and fats
- What trophic levels are primary carnivores in
- 3rd
- energy flows in how many directions
- one
- word equation for photosynthesis
- carbon dioxide + water sunlight/chlorophyll -> glucose + oxygen
- Energy leaves as heat and enters as
- light
- main difference between autotrophs and heterotrophs
- auto make own food and hetero cant so they consume others
- Example of a detritivore
- earthworm
- Carbon exits atmosphere as
- carbon dioxide CO2
- Grazing is
- herbivore eating a plant, carnivore eating the herbivore
- decomposers also known as ___________
- saprophytes
- Ecosystem
- abotic and biotic parts of an environment
- As you go down the trophic levels you lose
- heat
- 1st Trophic Level
- Producer
- Heterotroph
- Consumer
- What trophic levels are plants in
- 1st
- Autotroph
- Producer
- 4th Trophic Level
- Consumer Secondary Carnivore
- Consumers
- cant make own food. feed by consuming others
- How can humans effect food webs and chains
- removing part of a food chain, introducing new species, removing too much of an organism
- Producers
- make own food by converting suns energy into chemical energy
- 3rd Trophic Level
- Consumer Primary Carnivore
- Nutrients are continually recycled between the
- abiotic environment and biotic communities
- Decomposers
- obtain food by breaking down dead matter from any trophic level
- Respiration is the
- release of energy from food
- Organic Detritus Relationship is
- dead parts and wastes broken down by bacteria or fungi
- Is energy a flow or cycle
- flow
- Lettuce is a (level & producers or consumer)
- Producer and 1
- Large amounts of carbon are locked away in
- fossil fuels
- Detritivores
- obtain food by consuming dead matter from any trophic level
- chemical energy for
- new molecules and cells
- respiration forms ___ providing ______ for all living processes in the body
- ATP energy
- ... removes platns which could have soaked up CO2
- deforestation
- One way to block energy is to
- remove a food source
- __% of energy is passed to the next trophic level
- 10
- more energy =
- more consumers
- Herbivores obtain food by
- eating producers (plants)
