Basics for 100 Define ecosystem. A community and its abiotic environment

Basics for 200 Name 2 Kingdoms of life have autotrophs. Plants, Prokaryotes, Protists

Basics for 300 Give a key similarity and difference between detritivores and saprotrophs. Both consume non-living organic matter. Detritivores digest food internally Saprotrophs digest food externally and absorb the nutrients.

Basics for 400 Identify two food chains in which the brown owl (starred) is a tertiary consumer. Grass grasshopper mouse brown owl Tree caterpillar robin brown owl

Basics for 500 Identify each trophic level of the brown owl in different food chains and its final trophic level in the food web. Secondary consumer, tertiary, 5 th, 7 th, Final: 7 th

Populations for 100 What is the maximum number of individuals that an environment can sustainably support Carrying capacity

Populations for 200 Name each phase of this sigmoid population growth curve. (Lag), Exponential, Transitional, Plateau

Populations for 300 Name two density-dependent and two density-independent factors that could limit population growth. DD: disease, food competition, etc. DI: climate, number of shelter sites, etc.

Populations for 400 Give the correct formula for the factors affection population size at stage 1. Natality + immigration > Mortality + Emigration

Populations for 500 Explain what happens during the transitional phase of population growth. Following exponential growth, the increased population experiences harsher competition for resources. The population is still increasing (N+I>M+E), either N / I are decreasing or M / E are increasing. This is because it is more difficult to the resources needed to reproduce, or it is more difficult to get enough food to survive, or to avoid predators, etc.

Energetics / Cycles for 100 What is the primary initial source of energy for living things? Light

Energetics / Cycles for 200 Compare the use of energy and nutrients in livings things. Energy – passes once through a food chain, some continually lost (as heat) in inefficient conversions Nutrients – reused and recycled, the same atoms are always present

Energetics / Cycles for 300 Give three reasons for the “pyramid” shape of energy at successive trophic levels. 1. Much energy is lost as heat through cellular respiration 2. Not all living things are consumed by the next trophic level (die before they’re eaten) 3. Not all consumed materials can be assimilated (bone, hair, materials in feces)

Energetics / Cycles for 400 Name the processes that a) remove CO 2 from the atmosphere and b) add CO 2 to the atmosphere a) Photosynthesis b) Combustion, respiration

Energetics / Cycles for 500 100, 000 k. J/day/m 2 How much energy is available at the apex of the energy pyramid? 15% efficiency at each level 100, 000 x (. 15)3 = 337. 5 k. J/day/m 2

Greenhouse for 100 Which substance is responsible for the largest portion of the greenhouse effect? Carbon dioxide (CO 2)

Greenhouse for 200 What appears to be the primary result of increased levels of greenhouse gasses? Climate change / Global warming

Greenhouse for 300 Outline the precautionary principle and why it might apply to the human involvement in global warming. PP: If a change may have severe consequences, those advocating change bear the burden of proof; must show that the change will DO NO HARM before acting. Applies because human activities are likely to be the cause of climate change and the consequences of climate change are catastrophic disasters and many levels.

Greenhouse for 400 Give 3 consequences of global warming on the arctic ecosystem. 1. Increased range of and competition from temperate species 2. Increased success of pathogens and parasites 3. 4. Decreased area with arctic conditions Release of CO 2 / CH 4 from melting permafrost etc.

Greenhouse for 500 Explain greenhouse gasses as they related to solar energy Short-wave light mostly passes through atmosphere. It is absorbed by the Earth and re-emitted as long-wave (infrared) radiation. The greenhouse gases prevent from of the longwaves from leaving the atmosphere and entering space. The greenhouse gases absorb and reemit the longwaves, some of which are directed back towards Earth, which then further heat the surface.

Classification for 100 Write on the board the species name of an organism other than humans. Helianthus annus (or other correct answer)

Classification for 200 What are the seven levels of Linnaean classification in order? Kingdom, Phylum, Class, Order, Family, Genus, Species

Classification for 300 Give three major features that separate filicinophytes from coniferophytes. Filicinophytes: swimming sperm, spores, max. height 15 m, fronds, etc. Coniferophytes: pollen, seeds, max. height 100 m, needle-like leaves, etc.

Classification for 400 Identify each beetle species. A B C D 1. Has distinct stripes and/or spots on wing cases? Yes: Go to 2 No: Go to 4 2. Has a red background with black markings? Yes: Go to 3 No: Colorado potato beetle 3. Has long, easily visible legs and antenna? Yes: Bean leaf beetle No: Ladybug 4. Wing casings different color than head” Yes: Japanese beetle No: Bung beetle E A D E B C

Classification for 500 Give 6 animal phyla and a common name or example of each. Porifera – sponges Cnidaria – jellyfish Platyhelminthes – flatworms, tapeworms Mollusca – clams, octopi, snails Annelida – earthworms, segmented worms Arthropoda – insects, arachnids, crustaceans Chordata – humans, fish, birds
