Only complex, multi-celled animals can be classified as
vertebrate or invertebrate. Bacteria, being single-celled organisms
are neither vertebrate nor invertebrate.
Biofouling is the accumulation of living organisms on some
surface by the means of bacteria, fungi, protozoa, algae, and
invertebrates.
Why is stream health important?
Stream health is important because the health of the stream
effects the fish, invertebrates, and bacteria living in it.
What organisms kill weeds?
Bacteria, fungi, invertebrates, vertebrates, and viruses are
organisms that kill weeds. Bacteria, fungi, and viruses cause
damage and death through vectored diseases. Invertebrates such as
insects and vertebrates such as people terminate a weed's life
cycle and natural history by respectively serving as food sources
and unappreciated vegetation.
They are insects, therefore they are invertebrates.
What is a bacteria's waste?
Oxygen is produced by plants and some bacteria in photosynthesis, while CO2 is a waste productof all animals and plants. Nitrogen gases are produced by denitrifying bacteria and as a waste product, and bacteria for decaying yield ammonia, as do most invertebrates and vertebrates.
