It helps balance the ecosystems.Because without these components there wouldn't be an ecosystem.
Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive
cassie has just finished her session on the trampoline during pe. as she prepares to exit the trampoline, her vertical momentum is reduced by a series of three resistive impulses with the bounce mat. just prior to this series of impulses, her 48.5-kg body is moving downward at 8.20 m/s. on the first impulse, cassie experiences an average upward force of 230 n for 0.65 seconds. the second impulse of 112 n•s lasts for 0.41 seconds. the last impulse involves an average upward force of 116 n which cases a 84 kg•m/s momentum change. what vertical velocity does cassie have after these three impulses?

habits of an effective problem solver
read the problem carefully and develop a mental picture of the physical situation. if necessary, sketch a simple diagram of the physical situation to help you visualize it.
identify the known and unknown quantities in an organized manner. equate given values to the symbols used to represent the corresponding quantity - e.g., m = 1.50 kg, vi = 2.68 m/s, f = 4.98 n, t = 0.133 s, vf =
use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
identify the appropriate formula(s) to use.
perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
watson and crick brought together data from a number of researchers (including franklin, wilkins, chargaff, and others) to assemble their celebrated model of the 3d structure of dna. in 1962, james watson, francis crick, and maurice wilkins were awarded the nobel prize in medicine.
