Questions and Answers
What is a reason animals may migrate between habitats?
What is a reason animals may migrate between habitats?
- To increase competition for resources
- Only for reproduction
- For better food availability (correct)
- To improve genetic diversity
How does the classification of animals based on their physical characteristics differ from that based on their nutrition?
How does the classification of animals based on their physical characteristics differ from that based on their nutrition?
- Physical characteristics classify animals at a broader level than nutrition.
- Physical characteristics depend solely on their skeletal system type.
- Nutrition classifications can vary with habitats but physical characteristics remain constant.
- Nutrition classifications include specific diet types while physical characteristics do not. (correct)
Which of the following accurately describes the difference between Chordata and Anthropoda?
Which of the following accurately describes the difference between Chordata and Anthropoda?
- Chordates are primarily aquatic, while arthropods are exclusively terrestrial.
- Chordates have an internal skeleton, while arthropods possess an external skeleton. (correct)
- Chordates do not have legs, while arthropods do.
- Chordates have an external skeleton, while arthropods have an internal skeleton.

Study Notes
Introduction to Biology and Ecology of Living Organisms
- Course title: BIO1102
- Academic year: 2024/2025
- Lecturer: Dr. Arianne-Elise Harris
- Topic: Properties and Diversity of Animals
What Constitutes an "Animal"?
- Animals are a kingdom of multicellular organisms
- They are eukaryotic, possessing a nucleus and other membrane-bound organelles
- Animals are heterotrophic; they obtain nutrients by consuming other living things
- Animals undergo cell specialization, developing diverse cell types (e.g., nerve cells, skin cells)
- Most animals are diploid and reproduce sexually
Animal Cell Structure
- Animal cells lack a rigid cell wall
- Specialized animal cells contribute to tissue, organ, and system formation
Animal Cell vs. Plant Cell
- Animal cells are typically round or irregular in shape, 10-30 micrometers long
- Plant cells are typically rectangular or cubic in shape, 10-100 micrometers long
- Plant cells have a cell wall; animal cells lack this feature
Animal Characteristics
- Sensory: Detect and process environmental stimuli (light, sound, touch) via the central nervous system (CNS)
- Locomotion: Ability to move at some point in their life cycle, involving muscle and nerve coordination
- Digestion: Internal digestive systems for consuming and processing food; some use special tissues/organs for consuming other animals
- Other organisms absorb nutrients directly from the environment
Animal Characteristics (continued)
- Sensory organs
- Movement (locomotion)
- Internal digestion
Animal Life Cycle and Reproduction
- Most animals are diploid organisms
- Most animals reproduce sexually, with diploid adults undergoing meiosis to create sperm and eggs
- Some animals reproduce asexually (e.g., Cape honey bee, whiptail lizards)
- Life cycle begins with a zygote that develops into an embryo
Other Animal Characteristics
- Bodies can be covered in fur, scales, skin, or feathers, which vary across animal species
- Body shape is adapted for locomotion, digestion, and sensory functions
- Main forms of locomotion: swimming, flying, walking, crawling, and running
- Some animals may migrate between habitats for environmental factors not related to reproduction
Animal Classification
- Classification can be based on nutrition (e.g., carnivores, herbivores, omnivores, insectivores)
- Classification can be based on physical characteristics, includes Mammals, Reptiles, Fish, Insects.
Animal Classification Details
- Formal classification: used for classifying animals and includes categories like Domain, Kingdom, Phylum, Class, Order, Family, Genus, and species.
Animal Diversity
- Factors contributing to diversity:
- Habitat and Geographic location
- Temperature and humidity
- Seasonal variation
