What are the 5 different levels of the biosphere from smallest to largest?
What is species, population, community, ecosystem, biome. (each level makes up the next and our planet and everything in is known as the biosphere)
100
What are the 2 names for the first producers of energy-rich compounds that are later used by other organisms.
What is primary producers and autotrophs.
100
What is the difference between a food chain and a food web?
Food chains are steps that show transfer of energy through organisms by eating and being eaten in one single chain. Food webs are interacting food chains all linked together. (many food chains are in one food web because most organisms eat more than one thing)
100
What are the 4 biogeochemical cycles (how elements pass from 1 organism to another)?
What is biological process, geological process, chemical and physical process, and human activity. In biogeochemical cycles matter can be recycled/changed. (know about these processes)
100
What do decomposer do to contribute to food webs?
Decomposers convert dead remains to detritus (stuff detrivores eat) and during that process release nutrients that primary producers use to make energy.
200
What is the scientific study of interactions among organisms and between organisms and their physical environment.
What is ecology
200
What are the two main types of energy and the processes that correspond with them?
What is sunlight and chemical energy; photosynthesis and chemosynthesis.
200
What is the name of the primary producers consisting of the mixture of floating algae and attached algae?
What is phytoplankton. This is eaten by small fish normally.
200
What are the 3 Nutrient Cycles that pass necessary nutrients through the biosphere?
What is Carbon cycle, nitrogen cycle, and phosphorus cycle. (know these)
200
The branch of biology dealing with interactions among organisms and between organisms and their environment is called
Ecology
300
What are the 2 factors that are part of the enviroment and what is the difference between them?
What is biotic and abiotic factors. Biotic factors are LIVING parts of the environment that organisms interact with (animals, plants, bacteria). Abiotic factors are NONLIVING parts of the environment (sunlight, heat, rain, soil).
300
What are the 2 names for the organisms that rely on other organisms for energy and nutrients to survive?
What is consumers and heterotrophs.
300
What is a trophic level and how does it relate to ecological pyramids?
What is each step in a food chain or food web. It relates to ecological pyramids because ecological pyramids (there are 3 different types) show the relative amount of energy/matter in each trophic level.
300
What is the 1 cycle that does not pass on necessary nutrients like the other 3 cycles and what does it pass on?
What is the Water cycle. It passes on water (can enter the atmosphere through evaporation or transpiration)
300
Which of the following descriptions about the organization of an ecosystem is correct? A Communities make up species, which make up populations. b. Populations make up species, which make up communities c. Species make up communities, which make up populations. d. Species make up populations , which make up communities.
d Species make up populations , which make up communities
400
What are the 3 ecological methods?
What is observation, experimentation, and modeling. (know how they're used)
400
What are the 6 different types of consumers?
What is carnivores, herbivores, omnivores, decomposers, detrivores, and scavengers.
400
What are the 3 different types of ecological pyramids?
What is pyramid of energy, pyramids of biomass, and pyramid of numbers. PYRAMID OF ENERGY show the amount of energy available at each trophic level. PYRAMID OF BIOMASS show amount of living matter at each level. PYRAMID OF NUMBERS show number of organisms at each level in an ecosystem.
400
What is nutrient limitation?
When even 1 nutrient isn't available, even if there is enough sunlight and water, primary productivity in an ecosytem may be limited. The limiting nutrient is the specific nutrient that limits that productivity.
400
The total amount of living tissue within a given trophic level is
What is biomass
500
What is the lowest level of environmental complexity with living and nonliving factors in it?
ecosystem
500
What is taken in and produced during photosynthesis?
What is carbon dioxide and oxygen
500
What happens to energy as it goes through the Pyramid of Energy?
Most of the energy is stored or used while 10% is passed on to the next trophic level
500
What is the difference between the movement of energy and nutrients?
Energy flows in one-way while nutrients can be recycled, used, stored, and changed.
500
Nitrogen fixation is carried out primarily by
What is consumers
