Chapters 3+4
What is ecology and why is it so important?
What limiting 4 factors affect carrying capacity?
How is ATP useful to cells?
It enables cells to safely store energy
What ideas and scientists influenced Darwin?
Lamarck, Lyell, and Malthus
What do fossils reveal about ancient life?
Evolution over time
How do biotic and abiotic factors influence an ecosystem?
The abiotic factors control the biotic factors
How does biodiversity benefit an ecosystem?
Supports habitats for all species
What role do pigments play in photosynthesis?
They are light absorbing substances
What is the role of natural selection?
Drives evolutionary change
How do viruses reproduce and cause diseases?
The disease is caused by killing cells or disrupting cell function
Viruses reproduce by replicating its genome in a target cell
How does energy flow in an ecosystem?
Between organisms in food webs
How do population growth rates differ?
Exponential growth is endless growth, logistic growth goes up then levels out at the carrying capacity
How do organisms get energy?
What patterns of biodiversity did Darwin observe?
Species vary globally, locally, and over time
How is early Earth different from present-day Earth?
No ozone layer and was much hotter
What's the difference between a food chain and a food web?
A food chain outlies who eats who, a food web is every food chain in an ecosystem
What is ecological succesion?
What is the function of mitochondria?
They generate energy necessary to power cells
What is Lamarck's theory of evolution?
Organisms altered their behavior in response to environmental change
Explain the role of protists in the ecosystem
Suck up the carbon dioxide and produce oxygen
What is the 10% rule in an energy pyramid?
Each level in an ecosystem only gives 10% of its energy to levels above it
Identify limiting factors that depend on population density
Disease, pollution, competition, predation
What happens during the process of photosynthesis?
Describe how molecular biology can be used to trace the process of evolution
Molecular similarities provide evidence for shared ancestry
Describe the endosymbiotic theory
Some eukaryotic cell organelles evolved from free-living prokayrotes
