ecology

temp, water, breeding sites, territory, light, soil pH, salinity, mineral nutrients

underground stems that grow upward and sends out roots to get water as sand accumulates

water loss

roots grow closer to surface for O2, acquires carbon compounds/minerals to allow more H2O via osmosis, leaves secrete salts

tropical waters, 8.2 pH, 32-44 salinity, 23-29 C (optimal)

algae using CO2 & H2O to produce O2 in order to clean corals

treeless, permafrost, low nutrient soil

coniferous trees, nutrient topsoil, long winters, short summer

low rain, low vegetation

dry, unpredictable rain, fertile soil

broadleaf trees that loses leaves seasonally

niche a population can theoretically occupy based on tolerance, adaptaions, and limits

area a population actually occupies when in competition with other species

2 species cannot occupy the same niche ( can lead to elimination or resource partition)

microorganisms that can only survive in o2 free environments

organism that makes atp by aerobic respiration if 02 is present, but can ferment if no 02

require 02 for growth and use o2 as final electron acceptor in aerobic respiration

eats non-living organic matter

eats decomposers (bacteria, fungi) and digest externally

food is digested internally

uses 1+ method of nutrition (autotroph and heterotroph like euglena)

j curve

sigmoid (s shaped) pop slows as carrying capacity is reached

total population/total land area
