Habitats
Ecosystems are made up of these two factors.
What are abiotic and biotic?
Natural changes can also affect an ecosystem. Name three natural changes that can affect an ecosystem.
What is heavy storms, mudslides, temperature changes, or volcanic eruptions?
People can harm or help an environment. Name 4 ways people harm an environment.
What are mining for coal, habitat destruction from building and clearing, produce a large amount of waste, pollution of the air, land or water?
The dodo bird, golden toad, and Tasmanian wolf are examples of animals that did this.
What is became extinct?
Golden toad- drought, disease
Dodo bird- hunted and invasive species
Tasmanian wolf- overhunted
This is the gradual change of organisms in an ecosystem that follows an event such as a volcanic eruption is called this.
What is succession?
This is the difference between a community and a population
What is a community involves many different species and a population refers to only one species?
Consumers get their energy, either directly or indirectly, from this.
What are the producers?
These kind of organisms can be plants or animals and they take over space, food, limit growth, and resources of native organism.
What are invasive species?
Any living things that do not go through photosynthesis are referred to as this.
What are consumers?
These are 4 examples of biotic factors in a swamp ecosystem.
What are frogs, snakes, marsh grasses and fish?
In this ecosystem, the number and variety of plants and animals is larger than in any other kind of ecosystem. This is the word that refers to great variety of living things.
What is biodiversity? What is a rainforest?
If an organism lives in many types of trees and eat many different kinds of foods, they would be considered to have this.
What is a broad niche?
Lichens do this in order to begin the process of succession.
These guys produce an acid which breaks down rock turning it into a soil.
These organisms eat only producers such as mice, deer and rabbits
What are primary consumers or herbivores?
These would be signals that an ecosystem has become stable after years of succession.
What are grass, trees, birds, consumers?
Diversity is greater in this part of the world.
What is closest to the equator?
We are considered nature’s recyclers. Bacteria, beetles or worms can fall into this category.
What are decomposers?
This is considered a pioneer organism needed for primary succession to begin.
What are lichens?
These are decomposers that release enzymes to break down dead matter, releasing nutrients that enrich the soil.
What are earthworms?
The brown anole is invasive because it did this to the green anole.
An organism’s role or function in its habitat.
What is its niche?
These are 3 things that can affect the diversity in an ecosystem.
What are climate, location and people?
This is the main difference between primary and secondary succession?
What are in
primary succession begins on barren rock (soil isn’t developed enough) such as after a volcanic eruption?
In secondary succession, soil is still present such as an area where there was a forest fire?
All of the living and nonliving things that surround you make up your _____________________.
What is an environment?
Golden toads were once numerous in a part of the mountainous tropical forest of Costa Rica. This is what they think happened to them and the reason we have not seen them since 1989.
What is they think a period of drought dried up the pools where the toads laid their eggs and where tadpoles matured caused a rapid population decline. The drought also allowed fungus to grow and it harmed the toads to spread. Golden toads have not been seen since 1989 and are thought to be extinct?
