What is the difference between Biotic and Abiotic factors?
Biotic is living components of an ecosystem
Abiotic is the non-living components of an ecosystem
What is the difference between Autotrophs and Heterotrophs
Autotrophs produce their own food
Heterotrophs consume their food
What is photosynthesis and what is the equation?
Photosynthesis happens in autotrophs; happens in chloroplasts of plant cells
Equation: carbon dioxide + water ---Sunlight---> Glucose + Oxygen
What is the difference between inter and intraspecific.
inter is different species
intra is within one species
The size of the population determined by the limiting factor.
What is Ecology?
The study of ecosystems
What is a niche?
Role of a specific organism in an ecosystem
What is Cellular Respiration and what's the equation?
Cellular respiration happens in all organisms
Equation: Glucose + Oxygen ------> Carbon Dioxide + Water + ATP
Hunting strategies
Defensive (Active and passive)
What are the differences between Primary and secondary succession?
Primary: the growth of an ecosystem from a barren landscape/bare rock
Secondary: The growth of an ecosystem that happens after some kind of disturbance (Natural disasters)
What are the 2 types of biomes?
Terrestrial and Aquatic
What are 2 points about biodiversity?
Make ecosystems sustainable and resilient
Refers to having many different populations that can fill a niche.
What is a Carbon Cycle?
The cycle of available energy stored in carbon bonds
What is competition?
When different types of species compete for foods, shelter...
What is Ecological Succession?
Growth of an ecosystem toward a stable ecosystem
What are the four spheres?
Lithosphere, Hydrosphere, Atmosphere and Biosphere
What is the difference between Detritivores and decomposers?
Detritivores consume dead material and break it down internally
Decomposers Break down dead material externally and absorb nutrients
What is the Water cycle in order?
evaporation, condensation, precipitation, infiltration, transpiration, runoff
What is the 3 types of Symbiosis
Mutualism, Commensalism and Parasitism
Succession begins with pioneer species (Lichens)
What is the Ecological hierarchy in order?
Individual, Population, Community, ecosystem, biomes, and biosphere
What is a Trophic Cascade?
The loss of a species at higher trophic levels has a big impact on organisms at lower trophic levels.
What is the Nitrogen Cycle?
Nitrogen gas (atmosphere) --> Nitrogen-fixing bacteria (nitrogen gas to ammonia) --> nitrifying bacteria (ammonia gas into nitrates and nitrites) --> denitrifying bacteria (turn nitrogen back into nitrogen gas in the atmosphere)
What's the difference between the Food Chain and Food Web
Food Chain is an arrow pointing to the consumer
Food web is a set of interconnected food chains
What is the equilibrium?
