Big Idea 4

(Big Idea 4 #3) A grassland biome  is land covered mostly in grass rather than large shrubs or trees, like this large area.

(Big Idea 4 #3) An aquatic biome contains a large amount of water, and aquatic biomes are the most numerous of biomes in the biosphere.

(Big Idea 4 #4) A climax community is a community that has reached ecological equilibrium, not too little resources, not too big a population, for example, this could happen in a forest.

(Big Idea 4 #8) An endosperm is tissue made in the seeds of flowering plants before fertilization, so this would happen in plants like this orange tree.

(Big Idea 4 #11) This oak tree is a K-strategist, a large plant or animal that does not reproduce rapidly or in big numbers.

(Big Idea 4 #13) An ecological niche is the role of a plant or animal in it's community. A fruit fly's niche is helping to decompose fruit.

(Big Idea 4 #16) A pioneer species, such as a raspberry, is a species that rises up in an area that previously had no vegetation or lost it due to natural disasters.

(Big Idea 4 #18) Predation is the act of a predator feeding on  its prey, for example a snake feeding on its prey, usually some sort of bug.

(Big Idea 4 #19) An r-strategist is a species with a short lifespan that reproduces in a large numbers, such as a mouse, which reproduces rapidly but only lives for a short while.

(Big Idea 4 #20) Succesion is when new plants grow and succeed old plants that used to grow where they grow now, like these young trees that are growing where there used to be older oak trees.
