Big Idea 4

3. biomes - Biomes are areas with similar climactic conditions; below are some examples of biomes:


 Temperate grassland biome - A temperate grassland biome is a biome whose predominant vegetation is composed of grasses and shrubs; many of the fields in this area have grasses growing on them.




Stream/River biome - A river or stream biome is a freshwater biome that transport water to a marsh area, usually into lakes or oceans; this stream provides nutrients and minerals to the surrounding plants and animals in the area and also serves as a mean of irrigation for local farms.





7. detritivore - Detritimores are organisms that obtain nutrients by consuming decomposing plant/animal parts; fungi such as these mature Agaricus bisporus (Portobello mushrooms) are the primary decomposers in most environments.




8. endosperm - Endosperm is the name given to the tissue produced inside the seeds of most flowering plants; rice, when harvested, still contains the endosperm while the embryo and seed coat are removed from the seed.




9. introduced species - An introduced species is a species that is living outside of its native habitat as a result of human activity. Goats are an agricultural species that have been introduced very widely.




11. K-strategist - A K-strategist is an animal that produces few offspring that require parental care until they mature; some of the characteristics of K-strategists are large body size, a longer life expectancy, and the production of fewer offspring. Many mammals are considered to be K-strategists, such as these horses.




20. r-strategist - R-strategists are species that usually create an abundance of offspring, have a short maturation time and lifespan, and invent little in parental care. Weeds are an example of R-strategists because of their relatively short lifespan and high rate of producing offspring.
