Exploring Ecology Concepts and Notes

What is the study of ecology primarily concerned with?

• The study of human behavior in natural settings

• The study of geological formations

• The study of relationships between organisms and their environment

• The study of chemical processes in living organisms

Which of the following is NOT a characteristic of life?

• Ability to grow and develop

• Made of one or more cells

• Ability to reproduce

• Ability to create energy from nothing

What does it mean for an organism to be unicellular?

• It can divide into multiple organisms

• It consists of multiple cells

• It does not contain any cells

• It consists of a single cell

What is the role of DNA or RNA in organisms?

• They are the genetic material that carries instructions for life

• They provide energy for cellular processes

• They are only present in multicellular organisms

• They help in the digestion of food

What level of ecological organization directly follows the community level?

• Species

• Population

• Ecosystem

• Biosphere

What does biodiversity refer to?

• The variety of ecosystems within a geographical area

• The genetic similarity among species

• The variety of living organisms at all levels

• The classification system of living organisms

What is the purpose of a dichotomous key?

• To show the evolutionary history of organisms

• To classify organisms based on their genetic material

• To identify organisms based on specific characteristics

• To measure the biodiversity of an ecosystem

What distinguishes a cladogram from a phylogenetic tree?

• There is no difference between the two

• A cladogram is used only for plants, while a phylogenetic tree is used for animals

• A cladogram shows relatedness without specifying ancestors, unlike a phylogenetic tree

• A cladogram shows evolutionary relationships, while a phylogenetic tree does not

Which domain do dogs belong to?

• Protista

• Archaea

• Bacteria

• Eukarya

What is binomial nomenclature?

• A method for determining the age of fossils

• A two-name system for naming organisms, using their genus and species

• A classification system based on the physical characteristics of organisms

• A system that classifies organisms based on their evolutionary history
