Bacillus subtilis
Bacillus anthracis ( contains polypeptide capsule)
Streptococcus pneumoniae
Klebsiella pneumoniae
Haemplhilus influenza
Clostridium perfingens
Neisseria meningitidis
Pseudmonas aeruginosa

A. Recognize a problem
- 6 Jose saw bats catching insects after dark. He asked, “How do bats find the insects in the dark?
- 7 Justin wondered if dyes could be taken out of plant leaves, flowers, and stems.
- Rob read about growing plants in water wanted to know how plants could grow without soil is that
B. Form a hypothesis
- 1 Stephen predicted that seeds would start to grow faster if an electric current traveled through the soil in which they were planted.
- 2 Susan said, “If I fertilize my geranium plants, they will blossom.”
- 8 Kevin said, “If I grow five seedlings in red light, I think the plants will grow faster than the five plants grown in white light.
C. Test the hypothesis with an experiment-
- 4 Rene grew bacteria from the mouth on special plates in the laboratory. She placed drops of different mouthwashes on bacteria on each plate.
- 5 Kathy used a survey to determine how many of her classmates were left-handed and how many were right-handed.
D. Draw conclusions-
- 3 Jonathan’s data showed that household cockroaches moved away from raw cucumber slices.
Question is incomplete. Complete question has been attached.
Answer:
A simple aquatic food chain with the top predator as Baleen whale could look like:
Diatoms ⇒ Krill ⇒ Baleen whale
Only 10% of energy at one level is passed on to the next level. Hence, only 10% of biomass at one level is converted to biomass in the next level.
If a Baleen whale wants to gain 7.5 kgs at third trophic level, it means there should be 75 kg of Krill present in second trophic level. Similarly, there should be 750 kg of diatoms present in the first trophic level. Hence, 750 kgs of diatoms are required for a Baleen whale to gain 7.5 kgs.
