Chapter 1 Study Guide Biology BSCS

Front

What is the role of beneficial bacteria in the human body?

Back

Beneficial bacteria help with digestion, produce vitamins, and protect against harmful pathogens.

Front

What is exponential growth in bacterial populations?

Back

Exponential growth occurs when bacteria reproduce rapidly under ideal conditions, leading to a doubling of the population in a constant time period.

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of organisms in an ecosystem.

Front

What factors influence bacterial growth?

Back

Temperature, nutrients, and moisture are key factors that affect how quickly a bacterial population grows.

Front

Define a population in ecological terms.

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What is the difference between a population and a community?

Back

A population consists of individuals of the same species, while a community includes all the different species living in a particular area.

Front

How do bacteria contribute to nutrient cycling?

Back

Bacteria decompose organic matter, recycling nutrients back into the ecosystem for use by plants and other organisms.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability, allowing ecosystems to better withstand environmental changes.

Front

What is the impact of competition on species populations?

Back

Competition can limit population growth and distribution by reducing the availability of resources.

Front

How do environmental conditions affect bacterial survival?

Back

Bacteria require specific conditions such as temperature, pH, and moisture to survive and reproduce.
