Isnt it not desirable? you dont want friction to act when you push a box
1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
The appropriate answer is e. gymnosperm. Gymnosperms have seeds that are not protected by an ovary or fruit. A popular example of a gymnosperm are conifers. Another characteristic of gymnosperms is that they do not have bright flowers. The Greek word for gymnosperm literally translates to naked fruit. The seeds of these plants are open to the air and as such they are directly pollinated by the wind.
Ultraviolet, or UV, rays ,these are the rays that can cause sun damage to a person's skin in the form of sunburn. While a person cannot detect the sun's UV rays, he or she can detect the infrared rays via the sensation of heat.
Gamma rays - these are most often found in the core of the sun, during fusion. These rays lose frequency as they move towards the surface.
X-rays -
X-rays are emitted by the sun during solar flares.
Visible light -
visible light are radiation waves that are in the frequency range easily seen by the naked eye. Different wavelengths in the visible light spectrum make up different colors.
Microwaves -
microwave radiation waves emitted by the sun are primarily absorbed by the Earth's atmosphere.
Radio waves -
these waves have the longest wavelengths, and the sun is the brightest source of radio waves.
Answer:
An object can convert it's potential energy into kinetic energy. For example see the below figure, where potential energy of water has been converted into kinetic energy. A moving body can transfer some of its energy to set another body into motion. ... So, object what you are speaking about is nothing but energy (mass).
