1: What is primary productivity? What do we measure it in? (units)
- Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide
2: What are producers? Who are the main producers in the ocean? How is this measured in an aquatic environment?
- Producers manufacture carbohydrates within their cells. Any photosynthesizer, like a plant, is a producer. The main producers in the ocean are phytoplankton.
3: What is a trophic level? List and define the trophic levels. (Give examples) In which direction does the arrow go in a food web? Explain.
- Each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy
4: What is a food web? How is it different than food chains?
- Food web is a system of interlocking and interdependent food chains. The difference between food chain and food web is: Food chain is a relationship in the ecosystem where 1 organism eats or uses another as its source of food. example like snake eat mouse. Food web refers to overlapping food chains
5: Explain the limiting factors for growth in ecosystems. Explain logistic growth.
- An example of a limiting factor is sunlight in the rain forest, where growth is limited to all plants in the under story unless more light becomes available. This decreases plant photosynthesis.
6: What is the carrying capacity (K) of an ecosystem?
- The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment. In population biology, carrying capacity is defined as the environment's maximal load
7: What factors affect the carrying capacity of a population? Explain how wolves and elk populations are linked and how they will reach equilibrium.
- Food availiability, water, environmental conditions, and spaces are the factors that affect the carrying capacity of a population. Wolves and elk population are linked because wolves depend on elk as a food source. Equal amount of both species for wolves to survive and reproduce to reach equilibrium.
8: Summarize the story of the Whitebark Pine and how humans can impact an entire ecosystem by choices we make (directly or indirectly).
- Whitebark Pine is a location that contains a lot of pine nuts and squirrels. Due to the rise i temperature, the amount of nuts has been decrease. Bears and squirrels utilize the pine nuts as a food source; therefore the squirrel and bear population are affected by the loss of nuts as well.
