Using three characteristics of life, explain why bacteria are considered living organisms.
Growth: Bacteria grow and increase in size through cell division.
Metabolism: Bacteria carry out metabolic processes to convert energy from their environment, allowing them to grow and reproduce.
Reproduction: Bacteria reproduce asexually through binary fission, where one cell divides to form two identical daughter cells.

Among the different biogeochemical cycles, (1) which two cycles share the same stages, and (2) what are the names of those stages?
(1) The carbon & nitrogen cycle
(2) Decomposition, consumption.
I will also accept combustion as an answer too!

Draw the three patterns for population dispersion.
300
(1) What type of dispersion (spacing) pattern is represented in the picture?
(2) Would you say this is also an example of high density or low density?
(1) Random
(2) High Density

How many different colors are there in a regular bag of Skittles?
5!

Scientists believe they may have discovered a new plant species at the bottom of the ocean. They came to the conclusion it's biotic because the plant reproduces using seeds, can move it's leaves in the water, and doesn't need any cells! Would you support their conclusion or not AND why?
You should NOT! Because they are not using the correct characteristics of living things to support their findings. Living things DO NOT need to move to be considered biotic, but they DO NEED cells.

Identify a non-human organism who is involved in each of the cycles and which step they would be involved in. You CANNOT repeat organisms
Carbon - plants, photosynthesis or animals, cellular respiration
Water - plants, transpiration
Nitrogen - bacteria, nitrogen fixation

In a freshwater lake, the population of a certain fish species has been declining. Scientists observe the water temperature has increased steadily over the past decade due to climate change, human pollution from nearby agriculture has caused periodic algal blooms, reducing oxygen levels in the water, and increased fishing activity has reduced the adult fish population significantly.
(1) Identify a density dependent and independent factor from the example.
(2) Label which factors are biotic and abiotic.
Density Dependent Factor - human pollution and increased fishing activity (Biotic)
Density Independent Factor - water temperature increasing (Abiotic)

(1) Which biogeochemical cycle is this?
(2) How do you know?
(1) Nitrogen Cycle
(2) The nitrogen cycle relies heavily on bacteria, much more than the carbon cycle does, which is why this cycle includes multiple images of bacteria!

Animals are classified using scientific names, like Canis lupus for dogs or Aves for birds. What type of animal has the scientific name Boops boops? (yes it's a real name, I didn't make it up).
You don't have to be specific. Just name an animal.
Fish!
