BIO 112 Study Guide - Midterm Guide: Primary Production
Document Summary
Late successional adapt to lower light (grow taller) Early successional grow the fastest and are most competitive (typically show up first and complete life cycle fast) Leaf area index is smaller in late successional (put up more leaves on high branches, whereas early successional have denser amount of leaves) Species grow better on soils that previously grew their own species. Native species grew worse on own soil. Influence what communities look like by preventing certain plants from growing. Parasites are most likely to show up next to mother tree (where most seeds are) Producers are plants that absorb energy and nutrients. Eaten by primary consumers (herbivores) which are eaten by secondary consumers (predators) Biomass: mass of organisms (usually a whole trophic level) per unit area in ecosystem. Gross; rate of energy flow into a trophic level. Net: rate of production of new biomass by a trophic level.
