2. True, 3 True, 4 Trues, 5 False, 6 True, 7 True, 8 False, 9 True, 10 True

Explanation:

3. True , Electromagnetic waves have electric and magnetic energy while ocean wave have kinetic energy which is then converted into electrical energy.

4. True, the distance between all the wavelength is same until and unless it not dampened or attenuated or amplified.

5. False, Frequency measures the number of times an event takes place in a given time period.

6. True, the higher is the frequency , the more will be the energy

7. True, Gamma waves have highest frequency

8. False, our eyes could see only visible spectrum wavelengths

9. True, some object or surfaces reflect the wavelength while some absorb it.

10. True, all cosmic researches are driven by EM waves theory and related logic.

Which of the following statements is TRUE about competition between organisms with the same needs when resources are limited?

netineya [11]

Answer:

animals are the only organisms that compete for resources

Explanation:

this is due to the fact that plants take up resources passively, a method which doesn't require them to waste any energy, however in the case of resources, is not very effective. suppose there was a bit of water scarcity in your area, and a plant and you both need water for survival. obviously, the plant cant possibly do anything to receive these resources, as it is just a plant. its survival is based merely on the chance that you pour water into it. this is not the case for animals, which, like us, actively collect and gather resources, and use them to our advantage. therefore, animals are the only animals that compete for resources

he following is NOT true about trophic levels: Primary consumers belong to the first trophic level. Secondary consumers belong t

seraphim [82]

Answer:

Animals capable of feeding at many trophic levels will be able to survive if portions of their food supply are decreased or eliminate is not true of about trophic levels

Explanation:

This is because each trophic levels represent energy flow and supply of food to the organisms in the trophic levels. Energy are pass from one tropic levels to another as a result of source of food there. Plants majorly are the primary producers and the primary consumers depend on it. Therefore, if the source of food supply is eliminated in a trophic level, the organisms I'm the trophic level will not be able to survive.
