Identify how the energy flows up through the ecosystem. Describe how decomposers help to cycle matter in an ecosystem and their

NNADVOKAT [17]

Answer:

Decomposers are organisms that break down dead or decaying organisms, they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.

Consider an object with weight on the Earth W_earth. The gravity of the Earth is g. If it is moved to another planet with gravit

Mazyrski [523]

Answer:

$W_{Planet} = \frac{W_{Earth}}{g}\times a$

Explanation:

We know that weight of an object on Earth is,

$W_{Earth} = m\times g$

Thus,

$m = \frac{W_{Earth}}{g}$

where,

m = mass of an object, which is constant and is independent of gravity

g = acceleration due to gravity on Earth

On the new planet, gravity = a

Thus the weight of the object on the new planet will be

$W_{Planet} = m\times a$

$W_{Planet} = \frac{W_{Earth}}{g}\times a$

A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800.0 N on him. Th

ipn [44]

Answer:

a) $F_{fric}$ = 692 N

b) $F_{applied}$ = 932 N

Explanation:

a)

According to newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it. When there is no net force force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions.

$F_{net}$ ∝ a

$F_{net}$ = ma

$F_{applied} - F_{fric}$ = ma

Given data:

$F_{applied}$ = 800 N

Mass = m = 90 kg

acceleration = a = 1.2 m/s²

$F_{fric}$ = ?

800 - $F_{fric}$ = (90)(1.2)

$F_{fric}$ = 692 N

b)

According to newton's second law of motion,

$F_{net}$ ∝ a

$F_{net}$ = ma

$F_{applied} - F_{fric}$ = ma

Given data:

If we assume the same friction and acceleration between player's feet and ground as calculated in part a

$F_{fric}$ = 692 N

acceleration = a = 1.2 m/s²

We take the equal mass to the total mass of both the players because when the winning player push losing player backward, he exert force on the ground not only due to his mass but also due to the mass of losing player.

Mass = M = m₁ + m₂ = 110 kg + 90 kg

= 200 kg

$F_{applied}$ = ?

$F_{applied}$ - 692 N = (200)(1.2)

$F_{applied}$ = 692 + 240

$F_{applied}$ = 932 N
