LT# 2 - What role do photosynthetic protists, like phytoplankton, play in aquatic food chains?

• protists primarily function as heterotrophs, consuming other organisims

• protists primarily function as autotrophs creating food for the ecosystem

LT# 2 - Explain how fungi contribute to ecosystems.

• By producing oxygen through photosynthesis

• By decomposing organic matter and recycling nutrients

• By providing food for herbivores

• By fixing nitrogen in the soil

LT# 1 - Which kingdom includes organisms that are primarily multicellular, eukaryotic, and heterotrophic?

• Plantae

• Animalia

• Eubacteria

• Archaebacteria

LT# 3 - Describe the role of dichotomous keys in taxonomy.

• They provide a universal language for naming organisms.

• They help in identifying organisms by answering a series of questions.

• They classify organisms based on genetic similarities.

• They determine the evolutionary history of organisms.

LT# 3 - How do scientists use binomial nomenclature in taxonomy?

• To classify organisms into domains

• To assign a two-part scientific name to each species

• To determine the evolutionary relationships between species

• To describe the physical characteristics of organisms

LT# 2 - Compare and contrast the importance of Eubacteria and Archaebacteria.

• Archaebacteria are widely distributed across diverse environments like soil, water, and the human body, while Eubacteria are mainly found in extreme environments like deep sea vents, hot springs, and salt lakes

• Eubacteria are widely distributed across diverse environments like soil, water, and the human body, while Archaebacteria are mainly found in extreme environments like deep sea vents, hot springs, and salt lakes.

LT# 3 - Why is the classification of organisms into kingdoms important for understanding ecosystems?

• It helps in identifying the most dangerous species.

• It allows scientists to predict the behavior of organisms.

• It provides a framework for studying the roles and interactions of organisms within ecosystems.

• It simplifies the process of naming organisms.

LT# 3 - Which of the following best describes the process of taxonomic classification?

• Grouping organisms based on their ability to interbreed

• Organizing organisms into hierarchical categories based on shared traits

• Identifying organisms based on their physical appearance

• Naming organisms using common names
