global climate patterns are determined by sunlight and the plants movement in space. Produces temperature variations, air movement, and water evaporations. REquired by autotrophic plants for photosynthesis.
hydrogen concentration in the soil affects ability of plant roots to take up certain minerals and it can also affect benegicial fungi and bacteria. Limstone soils are basic, high sulfur soils are acidic. high pH=low acidity
supply needs for growth (nitrogen, phosporus, calcium, sulfur wtc.). deficiences produce disease excess leads to toxicity.
In Animals and PLants (reptiles)
Temperature (col blooded not in tundra because slow to accclimate), Water( need less, common in desserts), and food (need less, reduced predation)
a bounded physical space that an animal defends against encroachment, usually by members of its own species. It reduced competition for food, shelter, mates, and nesting.
