Answer with Explanation:

A food chain is a series of transmission of food and energy within an ecosystem. In a food chain the food and energy is transferred in the trophic levels. The trophic levels forms the hierarchy of feeding organisms in a food chain.

The producers come in the lowest trophic level. These are the organisms which can synthesize their own food by photosynthesis. They are the source of food and energy for a large diversity of animals and organisms of the other trophic levels.

The loss of plants, or producers from an ecosystem can reduce the population of primary consumers as they includes the herbivores. The decline in population of the primary consumers will reduce the population of secondary consumers which may include the carnivores.

When plants die they become food for the decomposer for example Lettuce, If all the Lettuce in someones field died the decomposer would get its nutriets and make the soil stronger, so if you plant more Lettuce and it survives the Consumer would get to eat the lettuce. Hope this helped! :)

Movies and TV shows sometimes portray a person being thrown backwards a sizable distance as a result of being struck by a bullet

MAXImum [283]

Answer:

R = 4.24 x 10⁻⁴ m

Explanation:

given,

mass of the person = 60.3-kg

mass of the bullet = 10 gram = 0.01 Kg

velocity of bullet = 389 m/s

angle made with the horizontal = 45°

using conservation of momentum.

M v + m u = ( M + m ) V

60.3 x 0 + 0.01 x 389 = (60.3 + 0.01) V

$V = \dfrac{3.89}{60.31}$

V = 0.0645 m/s

for calculation of range

$R = \dfrac{V^2sin 2 \theta}{g}$

$R = \dfrac{0.0645^2sin 2 (45^0)}{9.8}$

R = 4.24 x 10⁻⁴ m

the distance actor fall is R = 4.24 x 10⁻⁴ m

A 920-kg compact car moving at 92 m/s has approximately 3,893,440 Joules of kinetic energy. What is the change in kinetic energy

tensa zangetsu [6.8K]

Answer:

Change in kinetic energy = 3297280 J

Explanation:

Given that,

Mass, m = 920 kg

Speed of a car, v = 92 m/s

Kinetic energy, K = 3,893,440 J

If the speed of a car, V = 36 m/s

Net kinetic energy is given by :

$K_n=\dfrac{1}{2}mV^2\\\\=\dfrac{1}{2}\times 920\times (36)^2\\\\K_n=596160\ J$

The change in kinetic energy = 3,893,440 - 596160

= 3297280 J

So, the change in kinetic energy of the car is 3297280 J.

Desde una altura de 120 m se deja caer un cuerpo. Calcular a los 2,5 s i) la rapidez que lleva; ii) cuánto ha descendido; iii) c

stira [4]

Answer:

i) 24.5 m/s

ii) 30,656 m

iii) 89,344 m

Explanation:

Desde una altura de 120 m se deja caer un cuerpo. Calcule a 2.5 s i) la velocidad que toma; ii) cuánto ha disminuido; iii) cuánto queda por hacer

i) Los parámetros dados son;

Altura inicial, s = 120 m

El tiempo en caída libre = 2.5 s

De la ecuación de caída libre, tenemos;

v = u + gt

Dónde:

u = Velocidad inicial = 0 m / s

g = Aceleración debida a la gravedad = 9.81 m / s²

t = Tiempo de caída libre = 2.5 s

Por lo tanto;

v = 0 + 9.8 × 2.5 = 24.5 m / s

ii) El nivel que el cuerpo ha alcanzado en 2.5 segundos está dado por la relación

s = u · t + 1/2 · g · t²

= 0 × 2.5 + 1/2 × 9.81 × 2.5² = 30.656 m

iii) La altura restante = 120 - 30.656 = 89.344 m.
