Answer: 1. a. logistics model of growth
2. a. environmental conditions 
3. b. all limiting factors
4. b. water availability
Explanation:
1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably. 
Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources. 
2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.
3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor. 
4. d.  A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water. 
 
        
             
        
        
        
Answer: C. Their camera

Answer:
Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it's used for different purposes: Photosynthesis
