Clim8
What is the difference between climate and weather.
Climate is what you expect and weather is what you get!
Herbivorous animal distribution is important because it also affects the distribution of...
primary producers
What is the main distinction between primary and secondary succession?
The presence of a pre-existing older community. SOIL OR NO SOIL!!!!
What is the difference between a biome and an ecosystem?
A biome is a collection of ecosystems with a similar climate
Regions in which light can penetrate through the water and region in which light cannot penetrate are called the _______ and _______ regions respectively.
photic , aphotic
What are the greenhouse gases and what do they do?
CO2, Methane (CH4), Nitrous Oxides, H20, these contribute the average global temperature with the retention of heat within the earths's atmosphere
What are inter-specific and intra-specific competition and how do they change species fitness overall?
inter is between two different species and decreases fitness on both sides
Intra is within a single species and increases the species fitness
What is the first thing that happens in primary succession?
Pioneer species such as lichen populate the open niche
Which biome has the highest biodiversity?
Tropical rainforest, (Coral reefs if we are talking aquatic biomes)
What is the aquatic zone known as the "floor" which contains rocks and sediment .
BenTHICC Zone
What are the three main climate zones and why are they distributed as such?
Tropical, temperate and polar which is based on the curvature of the earth and the distribution of the suns rays on the earth.
Tropical most direct heat, polar is the least with temperate being in the middle.
List the 3 main classes of symbiosis and describe each interaction
Mutualism +/+
Commensalism +/0
Parasitism +/-
Is a flood considered primary or secondary succession and why?
Floods are secondary succession because it leaves the soil intact.
what is Perma-frost and where is it found typically?
Found within tundra biomes, perma-frost is a phenomena in which soil is frozen and therefore unusable due to the shunting of life within the soil composition.
The main primary producers within the aphotic zone are called.
Chemosynthetic bacteria/organisms which depend on hydrothermal vents in order to produce carbohydrates and sulfuric compound byproducts.
Hot air rises and cold air sinks due to hot air particles containing more energy and therefore as it bounces around it will have more space between molecules and be less dense relative to cold air molecules.
Niche partitioning via competitive exclusion
What is a climax community?
What is humus, what does it do and where are they typically found?
Decomposing leaf litter which provides food and shelter for small insects and nutrients for soil this is typically found within temperate forests.
Explain what happens to biodiversity as we get farther from the coast and why that happens.
Biodiversity decreases as we get further from the coasts because there is less nutrient runoff as we go toward the open ocean and therefore less materials to support a large primary producer population.
What is the cause for earths wind and ocean currents? Why do we get cold beaches in california?
Unequal distribution of solar energy that reaches the earth's surface.
Mixing of cold water from the northern pole.
Explain what a keystone species is and why otters are considered a textbook example
Keystone species maintains the structure of a food web. Often involving the primary producers in some way.
Otters eat sea urchins and therefore control their population. Sea urchins eat kelp which are the habitat of smaller organisms and the primary producer within the kelp forest. If otters are gone, sea urchins will be uncontrolled and therefore eat all the kelp. Then everyone dies :)
Describe the process of primary succession to climax community. Then describe the process of succession after a forest fire.
pioneer species >>> soil >>> weeds, plants, more plant, bigger plants, climax community
all plants die from fire then we get more weeds and plants and then climax community because we got soil.
Name at least 6 of the major terrestrial biomes
Tropical Rainforest, Tropical Desert, Temperate woodland, Temperate grassland, scrubland/chaparral, tundra, boreal/taiga forest, antarctic desert, savannah, Coniferous forest, Tropical Dry forest, etc.
Describe what kind of aquatic ecosystem a mangrove forest is and why they are important.
Wetland estuary, roots of mangrove trees habitat for small organisms and help to reduce sediment erosion and receding coastlines.
