Answer:

The Greeks attributed magnitude 1 to the brightest star seen in the night sky.

Explanation:

The Greeks created a system of magnitude based on the brightness of stars in the northern sky. It is not known for sure which astronomer was responsible for this, although many believe Hipparchus or Alexander Ptolemy is the creator.

These magnitude systems related the star's apparent brightness to its actual size. That way the brighter the star appeared in the night sky, the bigger its real size would be. For the brightest stars, magnitude 1 was associated.

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.
