Insects (mosquitoes, lice, fleas, bed bugs) and ticks are able to transmit a number of diseases caused by infectious agents: viruses (chikungunya virus, yellow fever, dengue fever, etc.), bacteria (Lyme disease, plague, etc.), parasites (malaria, sleeping sickness, leishmaniasis, filariasis, etc.)
 
        
             
        
        
        
The correct answer is it always occurs in a predictable pattern.
Ecological successsion is defined as a <em>change in the structure of species of an ecological community over a period of tim</em>e. The succession that begins in a new environment by uninfluence of pre-existing species is called primary succession. The disruption of pre-existing community because of succession is called secondary succession. Ecological succession happens in a predictable pattern. The ecological communities undergoes predictable change which creates a disturbance or initial formation of new habitat. This changes occurs in an orderly manner and can be best explained by the example of trees how they grow bigger and bigger.
 
        
                    
             
        
        
        
Answer:
Energy cannot be destroyed but moves from one state to another
Explanation:
In an ecosystem the dependence on energy is one of the main driving forces. Most animals and plants are always growing, changing location and moving and all these functions require energy. The energy after transformation from the sun, is referred to as biomass and the transfer of energy from one organism to another is called a food web. 
The answer is:
D.  Matter and energy can change forms and locations in ecosystems.

Answer:
living organisms need water to survive. all oxygen-dependent organisms need water to aid in the respiration process; some organisms, such as fish, cannot breathe outside its presence, while other organisms need water to help break down food molecules or generate energy during the respiration process.
Explanation:
water is good
