4.1 Part 1
Define Primary Succession
The gradual process by which an ecosystem develops and changes in a region that has not previously been colonized
Define Secondary Succession
The gradual process by which an ecosystem develops and changes in a region that has previously been colonized
Define Native species
A species that originated and developed in a specific ecosystem or region and has adapted to living in that area
Define Rewilding
is the process of restoring an area of land to its natural uncultivated state
Define microhabitat
A habitat that is small or limited in extent and that differs from the surrounding habitat.
Define Gross Primary Productivity
The rate at which producers convert solar energy into biomass
Define Net Primary Productivity
The rate at which producers convert solar energy into biomass minus the loss of energy through respiration
Define Invasive species
a species that is able to outcompete other species, causing changes to an ecosystem's balance
what is Captive Breeding?
the breeding of endangered species in captivity, with the goal to releasing them back into a protected wild area.
Define cascading change
a top-down process, where a change made at the top of a food web makes a change throughout the food web and the ecosystem
Name the 4 major terresrtial biomes
Desert, Grasslands, Forest, Tundra
What trophic level is a snake on
Secondary Consumer
Name 3 impacts a Invasive species can cause
Grazing, Competition, Predation, Disease transmission, Parasites and suppression of growth are all correct
Some problems that can occur to a species due to Captive breeding
small population can lead to increased chances of inbreeding and result in a selection for weak genetic traits.
at least 2 Reasons to preserve rainforest and managing them sustainably
Maintaining biodiversity, protecting the ongoing production of resources, managing climate change and managing local water quality and protecting the local water cycle.
How is energy lost between trophic levels
Heat due to respiration and excretion
What are the 4 trophic levels
Primary Producers, Primary Consumers, Secondary Consumers, and Tertiary Consumers
What are some Limitations to the IUCN Red list:The International Union for Conservation of Nature?
There may be species that should be on the list that are not. Documentation regarding sources of data not always properly maintained and so may not be valid.
Evolutionarily Distinct and Globally Endangered species (EDGE) purpose?
Its purpose was to raise funds and awareness of the need for some EDGE species, such as the giant panda or the elephant, are well known.
How does Deforestation contribute to Climate change?
Forests store vast quantities of carbon and once they burn the carbon is released back into the atmosphere
What percent of energy is transferred to the next trophic level
10%
What is the difference between a biome and ecosystems
Biomes are large zones characterized by its soil, climate, vegetation and wildlife
Ecosystems are made up of all the organisms and the physical environment in which they interact
What does CITES stand for and what’s its purpose?
CITES:Convention of International Trade in Endangered Species of Wild Fauna and Flora
Purpose:To protect endangered plants and animals, and ensure sustainable trade in species.
A real world example of an Extractive reserves?
An example of an extractive reserve is the Chico Mendez reserve in Brazil.The land is publicly owned. However, the people who live in the forests, and whose livelihoods and culture depend on access to its resources.
->An relevant example will also be accepted
How can Debt reduction be an international approach to managing rainforests?
LICs which often have high levels of debt so some HICs have agreed to write off debt and In return, the HIC asks for the protection of an area of rainforest.
