Photosynthesis and Cellular Respiration
Is this equation photosynthesis or cellular respiration?
6CO2 + 6H20 --> C6H12O6 + 6O2
What is it called when a population has reached its maximum resource load?
Carrying capacity
What percent of energy is transferred to each part of the trophic pyramid?
10%
What type of ecological succession starts with bare rock?
primary succession
What is a heterotroph?
consumers who eat other things (omnivore, carnivore, herbivore)
In plants, what helps the plant conserve water when water is limited?
the stomata
What is a niche?
A unique role a species plays in an ecosystem.
What is an animal that doesn't have a predator called?
apex
How do you determine if an ecosystem has a high level of biodiversity?
count all of the species
What is a pioneer species in primary succession?
moss or lichen
What is the chemical formula for glucose?
C6H12O6
What is the difference between exponential growth and logistical growth in an ecosystem?
Which direction does the arrow point in a food chain or food web?
toward the predator that is receiving the energy
Where is the most carbon stored on earth?
fossil fuels
What is an ecosystem?
Abiotic and biotic things interacting
How are photosynthesis and cellular respiration connected?
The equations are opposite, what humans need is opposite of what plants need.
What are the 3 types of symbiosis?
mutualism, commensalism, parasitism
Which type of organism has the most biomass on the planet?
producers
What gas is released in the nitrogen cycle during Nitrogen fixing phase?
Ammonium (NH4)
What is symbiosis?
the ecological relationship between different species in an ecosystem
How does the flow of carbon work in photosynthesis?
Carbon flows from the atmosphere and is absorbed in plants. It becomes part of glucose and animals ingest it.
What are 3 different limiting factors?
natural disaster, predation, competition, food, reproduction, invasive species, immigration, emmigration
Which of the following is the secondary consumer in the food chain:
lily pad --> snail --> frog --> alligator
frog
What are the 2 main processes used during the carbon cycle?
photosynthesis or cellular respiration
What does biogeochemical cycle mean?
How the earth, molecules and living things exchange energy over and over again on Earth.
