Question

unit 1 lesson 1a gn: life as a hunter: learning target students will be able to provide a description of factors of scientific method as well as levels of organization. students will be able to describe the pros and cons of group vs solo hunting behavior. warm up 1) do lions live in a group or in isolation from other lions? explain your explanation. 2) do lions play specific roles in the ecosystem? explain your answer. inference inference is a conclusion reached on the basis of evidence and reasoning mental process logical interpretation or explanation of the observations can be based on second - hand experience observation observation is the act of paying close attention to something in order to gain information uses the five senses help to reach an inference experienced first - hand practice inference vs observation 1) the tire is flat: inference vs observation 2) the vehicle is in a desert: inference vs observation 3) the truck is old: inference vs observation 4) there is rust on the wheel well: inference vs observation 5) i hear thunder: inference vs observation 6) it will rain soon: inference vs observation what are the characteristics of living things? how do these characteristics support living things? 1. one or more cell(s) 1. all organisms need one or more cells that perform functions to keep living things alive.

Explanation:

1. Do lions live in a group or in isolation from other lions?

• Lions are social animals and usually live in prides (groups). This is supported by their hunting - cooperative behavior and social structure.

1. Do lions play specific roles in the ecosystem?

• Lions are apex predators. They help control the population of herbivores, which in turn affects the vegetation and other species in the ecosystem.

1. The tire is flat: Observation. It can be directly seen.
2. The vehicle is in a desert: Inference. It is a conclusion based on other factors like the appearance of the surroundings which may not be directly observable as “desert” at first glance.
3. The truck is old: Inference. It is a judgment based on various aspects like wear - and - tear which is not a direct observation of “oldness”.
4. There is rust on the wheel well: Observation. It can be directly seen.
5. I hear thunder: Observation. It is a direct perception through the sense of hearing.
6. It will rain soon: Inference. It is a prediction based on the observation of thunder, not a direct observation.
7. Characteristics of living things and their support: One or more cells are essential as they perform vital functions like metabolism, growth, and reproduction which keep living things alive.

Answer:

1. Lions usually live in groups (prides).
2. Lions play the role of apex predators, controlling herbivore populations and influencing the ecosystem.
