What is an ecosystem?
Correct Answer
A. All of the biotic and abiotic factors in an area.
Explanation
The correct answer is "All of the biotic and abiotic factors in an area." An ecosystem refers to the interaction between living organisms (biotic factors) and their non-living environment (abiotic factors) in a specific area. This includes the relationships, energy flow, and nutrient cycling among plants, animals, microorganisms, water, air, soil, and other components of the ecosystem. It encompasses both living and non-living elements that influence and sustain life within a particular ecological community.
2.
Abiotic means
Correct Answer
B. Nonliving.
Explanation
The term "abiotic" refers to factors or elements that are not associated with or derived from living organisms. It pertains to nonliving components of the environment, such as temperature, sunlight, water, air, and minerals. These abiotic factors play a crucial role in shaping ecosystems and influencing the distribution and abundance of living organisms. Therefore, the correct answer is "nonliving."
3.
Biotic means
Correct Answer
A. Living.
Explanation
The term "biotic" refers to living organisms or factors that are derived from living organisms. It encompasses all living things, including plants, animals, and microorganisms. Biotic factors play a crucial role in ecosystems as they interact with each other and with the abiotic (non-living) components of the environment. Therefore, the correct answer is "living."
4.
Organisms have relationships can can help, hurt, or not effect one another.
Correct Answer
A. True
Explanation
The statement is true because organisms indeed have relationships with each other that can be beneficial, harmful, or have no effect. Organisms interact with each other in various ways, such as through predation, competition, mutualism, or commensalism. These relationships can have significant impacts on the individuals involved and the overall ecosystem.
5.
A relationship where one organism is helped and the other is hurt is called
Correct Answer
C. Parasitism
Explanation
Parasitism is a type of relationship between two organisms where one organism benefits (the parasite) while the other organism is harmed (the host). The parasite relies on the host for resources and survival, often at the expense of the host's health or even its life. This type of relationship is characterized by the parasite benefiting and the host being negatively affected.
6.
The abiotic and biotic factors in an ecosystem
Correct Answer
B. Effect each other.
Explanation
The correct answer is "effect each other" because abiotic factors, such as temperature, sunlight, and soil composition, can directly impact the distribution and behavior of biotic factors, such as plants and animals. Similarly, biotic factors, such as predation and competition for resources, can influence the abundance and diversity of abiotic factors. Therefore, there is a mutual relationship between abiotic and biotic factors in an ecosystem, where they interact and influence each other's existence and functioning.
7.
The Greek word bio means
Correct Answer
A. Life.
Explanation
The Greek word "bio" refers to life. This can be inferred from the fact that "bio" is derived from the Greek word "bios," which means life. Therefore, the correct answer is life.
8.
A population is
Correct Answer
C. A groups of individuals.
Explanation
The correct answer is "a group of individuals." This is because a population refers to a collection of individuals of the same species living in a particular area at a given time. It is not a group of communities or biomes, as those terms refer to larger ecological units. A population, on the other hand, focuses on the individuals within a species and their interactions within a specific geographic area.
