Answer:

b) 1,000

Explanation:

In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.

Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.

Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.

= 10/100 × 10,000 = 1000 units of energy.

An object has a kinetic energy of 25 J and a mass of 34 kg. How fast is the object moving?
Andreyy89
Kinetic energy is the energy possessed by an object with mass when in motion. It is calculates by 1/2 the product of the mass of the object and the square of its velocity.

KE = 1/2 (mv^2)
25 = 1/2 (34)(v^2)
v = 1.21 m/s
