Chen,Patrick - Biology Scavenger Hunt Big Idea 4

7. Detritovore (Uca pugnax): A detritovore is a heterotroph that feeds off of nonliving organisms. Here, the fiddler crab is decomposing the dead seagull.

20. r-strategist (Acanthinucella punctulata): Species that are r selected have high growth rate and produce many offsping. The hermit crab produces lots of offspring so it is a r-strategist.

18. Population (Paracheirodon innesi): A population is a group of individuals in the same given area at a given time. The picture shows the population of neon tetra living in the fish tank.

9. Introduced Species (Roystonea regia): An introduced species is a species living outside its native range. The royal palm is not native to Sacramento but instead introduced to the area.

3. Biome: A biome is a major terrestrial ecosystem. The biome of Carmichael is defined by a lot of trees and semi mild climate.

6. Competition (vinca minor): Competition is when two or more organisms compete over resources of a specific place. Here, the common periwinkle is taking the resources of other flowers. 

13. Niche (glyptoperichthys gibbiceps): The niche is the role that a particulary species has on the environment. In the fish tank environment, the plecostomus' niche is the clean the tank of green algae.

17. Pioneer Species (bryophyta): Pioneer species are the first growers of a previously uninhabitable environment. Moss are often pioneer species and start the nutrient cycle.

8. Endosperm (Zea mays var. everta): An endosperm is a storage tissue inside to seeds of angiosperms. The popcorn revels the endosperm of corn.

11. K-strategist (homo sapiens sapiens): Species that are K selected have few offspring, low mortality, and population is approaching carrying capacity. I am a human and humans are k-strategists because of low fecundity.
