What is the ladybug’s fundamental niche and realized niche?
If I describe it’s habitat as a garden, would the fundamental niche be the garden, but the realized niche be the leaf? Or is this a bad example of a habitat to start with?
A fundamental or “potential” niche of a creature includes all of the places it can live in, having sufficient food, a safe place, etc, It is not a specific area but the system a plant or an animal lives in.
See Figure 9g-1

For a ladybug all areas with lots of green plants, e.g. roses, oleander, milkweed and broccoli. and lots of of aphids are fundamental niches, their habitat.
“Habitat
Ladybugs live in trees, shrubs, fields, beaches, and in homes. In the fall they crawl to winter sites. A few to several hundred gather for the winter. The winter gathering spot may be at the base of a tree, along a fence row, under a fallen tree, or under a rock. In the mountains large numbers of up to 500 gallons of beetles may move in together for the winter.”

The realized niche of your ladybug is ( the rose bush ) in your garden.
