Purpose of Classification
What is the main reason scientists classify animals and plants?
To group them based on similarities.
True or False: An invertebrate has a backbone.
False
Which of the following is a mammal: a lion, a frog, or a snake?
Lion
True or False: Plants can make their own food using photosynthesis.
True.
Why is biodiversity important for species survival?
It helps maintain ecosystem stability and allows species to adapt to changing environments.
True or False: Classifying animals is mainly to give them new names.
False
Which of the following is a vertebrate: a jellyfish, a bird, or a spider?
Bird
Which group does a cold-blooded animal with scaly skin belong to?
Reptiles.
Which kingdom includes organisms that create their own food?
Plant Kingdom.
How do animals and plants work together in an ecosystem?
Animals rely on plants for food and oxygen, and plants rely on animals for pollination and seed dispersal.
Why do scientists use similarities to group living things?
To organize and understand the relationships between different species.
What is the main difference between vertebrates and invertebrates?
Vertebrates have a backbone, while invertebrates do not.
What makes amphibians different from reptiles?
Amphibians live part of their lives in water and part on land, and they have smooth, moist skin, while reptiles have scaly skin and lay eggs on land.
What is one thing plants can do that animals cannot?
Plants can create their own food through photosynthesis.
What might happen if there is a lack of biodiversity in an ecosystem?
The ecosystem could become unstable, and species may face extinction due to lack of adaptation and food sources.
Name one benefit of clarifying animals and plants.
It helps scientists communicate more effectively and understand evolutionary relationships.
Give one example of a vertebrate and one of an invertebrate.
Vertebrate: Dog; Invertebrate: Jellyfish.
Give one example of an animal that is both a herbivore and a mammal.
Elephant.
How do plants support other organisms in an ecosystem?
Plants produce oxygen and provide food for herbivores and other organisms.
Give an example of how biodiversity benefits a species.
Biodiversity provides a variety of food sources, which helps species survive when one source becomes scarce.
What might happen if scientists didn't classify animals and plants?
It would be harder to study, understand, and communicate about different species.
Why is having a backbone important for vertebrates?
The backbone provides structural support and protects the spinal cord.
What are the main characteristics of mammals?
Mammals are warm-blooded, have fur or hair, and most give live birth and feed their young with milk.
What is the process called where plants make their own food using sunlight?
Photosynthesis.
How does biodiversity affect the health of an ecosystem?
High biodiversity ensures that ecosystems are more resilient to changes and disturbances, supporting all species within the system.
