Human Ecology Quiz 1

1. What is ecology?

The interrelationship between the biotic and abiotic systems.

The community of plants, animals, and microorganisms that interact with each other and their environments.

The study of the relationships between organisms and their environments

None of the above

Ecology is the study of the relationships between organisms and their environments. This field of science focuses on understanding how living organisms interact with each other and with their surrounding physical and biological factors. It involves studying the interrelationship between the biotic (living) and abiotic (non-living) components of ecosystems. Through ecological research, scientists can gain insights into the dynamics and functioning of ecosystems, as well as the impacts of human activities on the natural environment.

2. One's phenotype is based on which of the following?

Genotype

Environment

Fitness

A & B

A & C

One's phenotype is determined by a combination of their genotype and their environment. The genotype refers to the genetic makeup of an individual, which includes the genes they inherit from their parents. The environment includes factors such as nutrition, exposure to toxins, and experiences that can influence how genes are expressed. Both the genotype and the environment play a role in shaping an individual's physical characteristics and traits, making options A and B the correct answer.

3. __________ is the genetic composition of an individual.

Genotype refers to the genetic composition of an individual, which includes all the genes and alleles present in their DNA. It determines the specific traits and characteristics that an individual inherits from their parents. The genotype can influence various aspects of an individual's physical appearance, behavior, and susceptibility to certain diseases. It is an essential factor in understanding the inheritance patterns and genetic variations within a population.

4. ______________ is the degree to which an individual produces viable offspring.

Fitness is the degree to which an individual produces viable offspring. This means that an individual's fitness is determined by their ability to successfully reproduce and pass on their genes to the next generation. Those individuals who are more successful in reproducing and producing offspring that survive and reproduce themselves are considered to have higher fitness. Fitness is an important concept in evolutionary biology as it directly relates to the survival and reproductive success of individuals and the overall adaptation of a species to its environment.
