Fill in the Blank:
1. Marine, Freshwater, Terrestrial are the 3 types of the basic type of ecosystem.
2. Temperature, sunlight and soil pH are a list of abiotic factors that affect the
distribution of organisms.
Short Answer:
1. Explain species, population, and habitat.
◦
• Species: Speciation can happen between two different species, for
example like when a horse breeds with a donkey to produce a
sterile mule.
• Population: There are about 100 thousand
zebras living in the savannah. (number not stated to scale; not
true)
• Habitat: The habitat of wildebeest is the savannah
and temperate grasslands of eastern and south-eastern Africa.
2. How does the food web contribute to thermodynamics?
◦
Law of conservationenergy can be loss although not destroyed, but
lost when going on to the next trophic level (transfer energy); it’s
not lost, goes into the environment due to Law of conservation.
