Objectives  Identify the 4 unifying themes of Biology.  Explain what characteristics an organism must have to be considered alive.  Identify the 4 unifying themes of Biology.  Explain what characteristics an organism must have to be considered alive.

Unifying themes of Biology  1. All living things share common characteristics  2. All living things share common needs  3. Living Things meet their needs through interactions with the environment  4. The types and numbers of living things change over time  1. All living things share common characteristics  2. All living things share common needs  3. Living Things meet their needs through interactions with the environment  4. The types and numbers of living things change over time

1) All Living Things Share Common Characteristics a) Made of 1 or more cells. Unicellular Small, hard to see directly exchange nutrients and waste with environment Multicellular Work together cells have specialized jobs and work together to keep organism alive

Common Characteristics (cont.) b) Organized  All parts work together to take in nutrients and remove waste  Body plan allows it to survive in its environment

Common Characteristics (cont.) c) Growth and Development *Cell division and cell differentiation*

Common Characteristics (cont.) d) Responds to stimuli

2) All Living things share common needs. a) We need energy!!  Energy is the ability to do work.  The sun is the ultimate source of energy!

Energy (cont.)  Can come from food and is converted into usable form, think calories  Energy moves along food web, only 10% of energy transferred to each level

How do we get our energy?  Autotroph (Producers)  Heterotroph (Consumers)

Common needs (cont.) B) Homeostasis: Regulation of an organism’s internal conditions to maintain life Blood Pressure Blood sugar levels Temperature

Common needs (cont.) C) living space i.Serves as protection ii.Sources of nutrients iii.Area to grow and develop

All organisms need to Adapt D) Adaptations:  characteristic of an organisms that allows it to better survive in its environment *Organisms within a species must adapt to changing environments or they will become extinct!!* Ex: A cheetah’s speed, camouflage, etc. Common needs (cont.)

Can you spot the adaptation in each picture?

3) Living Things meet their needs through interactions with the environment  A) Environment: everything that surrounds an organism. i.Living factors (biotic factors) ii.Non-living factors (abiotic factors)  Ex: sunlight, temperature, climate, rocks, etc.

Look at the following picture and list 3 abiotic factors & 3 biotic factors

Interactions with the Environment (cont.)  B) Species Interactions- 2 or more things affecting each other.

Think-Pair-Share  Name at least 5 DIFFERENT interactions occurring in the following picture.

Do Now  List 2 characteristics that all living things share.  List 2 needs that all living things share.  What is the scientific term for a living thing? Non-living?  List 2 characteristics that all living things share.  List 2 needs that all living things share.  What is the scientific term for a living thing? Non-living?
